Now to pack this all up as best as possible, OCD engage...
Oh boy, I may not want to open such a perfectly packaged box!
Look forward to getting it!

Are you setting things up, or is the client?
If you are, then you could potentially configure this in DNS. As far as accessing the data from the local network, the only thing that I can think of is to run some sort of a gateway service.
One possible route, not sure how difficult this may be for some, is to use a router running something like DD-WRT and running your own custom service on them.
I'm not sure how much help I am being here.

You could try putting the netduino on its own subnet, but that is only going to help if you don't need to access it locally. You could put the PC on both subnets too if you do.

I can confirm that the chip is indeed working as he has it wired, as it worked on my arduino. We just can't seem to figure out exactly how to code this in .NET.

I am just guessing at how this keypad is wired, but I'm fairly certain that you won't be able to do this. If you want to reduce the lines you would need to have to encode the key presses. I currently have a 4x3 keypad with 7 terminals. This is because there are 3 connections for the columns and 4 for the rows. In your case, I'm guessing that there is 4 connections for the columns and 4 for the rows. In order to detect the key presses, you need to scan for them. For very short intervals, you need to bring each of the columns, one at a time, high and scan the rows for their state. This will allow you to detect which key in a column is pressed. The image below shows how the connections on my 4x3 keypad correspond to the buttons.
If you want to connect this directly to the Netduino, you are going to need all 8 connections (less if you dont need every key, but what would be the fun in that?).
If you want to use as few pins as possible on your Netduino, then you are going to have to have some sort of external circuit to do this encoding for you. Personally, I would use a cheap PIC and then have that interfaced to the Netduino, though you could definitely use a Netduino mini for the purpose. There are even chips dedicated to this task.

I have to do this sometime in the near future (keep putting it off). When I do, I'll be sure to post an example circuit and code for the PIC version for the benefit of all!

This is quite the interesting idea, and I don't think I would have ever thought of doing it in this way. I will have to try this out at some point.

I have not heard of any progress in this, though I probably have to paid as much attention to it as I should seeing as I think this is an extremely important thing to be done for all micro-controllers in the next year or so.

This looks great for those who want the modules!
I'm glad you added the base shield, but I am curious about whether the Netduino will be shifting more to modules or simply have a module friendly version. I guess my biggest question is, can we expect to see a Netduino Plus with this same speed at any point?

Hrm, this is a good question. I have to do this at some point to make my client more stable, just been lazy.
#25476 How much current can you draw from the 5v pin?

Also my project behaves differently when running from a USB charger as opposed to connected to a PC. The timings appear to change on the UART which should be fixed surely or else it wouldn't work properly.
Yes, pretty sure that could be a power issue.
I would not be comfortable with a constant 800mA draw, even if its not shutting down, I don't like my board to be getting so warm. This could cause the board to get quite warm. I like to power via 5V rail with either a PC power supply, or a similar stand alone supply, and only use the on-board regulator for small projects.Well it states that the 5v regulator on board is good to 800mA we know that the controller uses about 250 so that leaves 550mA to stay in the current spec. So as long as the on board reg doesn't overheat we're good. The reg will shutdown in the event it gets too hot so it should be fine. perhaps my issues could be insufficient supply decoupling.

Haha, well I guess its funny. I worry about my Netduino Plus ($50) getting too hot, but my dual nVidia GTX580 video cards ($500ea) I allow to run at 196 F....
Maybe I do worry too much, just had issues with my board being so hot i couldn't touch it, although I have no idea what my current draw was that time.

I would suggest you check out some AJAX examples.
You would need to have javascript poll the server (netduino) every few seconds to update the data. This would require a page that outputs only the relevant data in some format such as JSON, XML, CSV, etc....

#21288 Beta driver for .NET MF 4.2 RC3+

Beta Firmware and Drivers
I got a BSOD, and the general long delays during deploys. Switched to dev'ing in a winXP VM for now. From a deployment / stability standpoint, this is working great! From a UI standpoint, I HATE XP.
Also, if you flash the bootloader, when you should be plugging in and deploying the netduino firmware, it is not recognized and I had to remove the device and delete this driver for MFDeploy to see the device.
FYI, I'm running Win7 x64 and my devices are Netduino plus.

After some extensive messing, I finally got my vid card issue fixed, which turned out only to be aggravated by any USB device. I have not tried the netduino on my win7 x64 machine yet as I have all of my stuff setup within winXP x86. Will try it again one of these days when I get this magical thing called time.

Ok, I have been using this driver for a few weeks and have some more feedback.
Seems that it is conflicting with my nVidia drivers. Launching a game will cause the graphics driver to crash with in minutes, but only when the netduino is plugged in. Otherwise it will lock up once every so often. When the netduino is not plugged in, I don't seem to be having this problem at all.

If irc is something that you really want to use, I have been idling in the #netduino channel on freenode. Usually nobody is there, but a few people do stop by every now and then. Hopefully there will be an official irc channel someday.

because 10/100 networking only uses 6 wires (3 pairs):
Correction, only uses 2 pairs. Orange/Orange White and Green/Green White are used for transmitting and receiving data. A lot of commercial POE systems actually send power over two pairs to achieve higher power transfer. As a telecom contractor, there were many times where I used the Brown/Brown White and Blue/Blue White pairs as either a second Cat 5 cable, a phone line or two, or to bring both DSL lines into the modem that we used for IPTV service. May not be the standard, but the standard doesn't work when you only have one existing Cat 5E and no options for running a new one.
That being said, always be aware of how the jack is wired on any device you are plugging into in the event that that device has the Brown and Blue pairs grounded or otherwise used. Last thing you want to do is short your power supply out! The CAT 5E standard allows for Blue pair to be used as a voice(standard phone), and you may find networking devices passing this through. Some people may see the possibility to use this as a potential power source for your devices while not paying for the electricity if you have a land line, and while this is possible, I would advice against it.
