I'm working on a project where we are going to be having a large number of Netduino devices talking to our SaaS Platform. When we ship the units, they are going to talk to our platform using some simple web services, but we have to uniquely identify each unit.
Is there *any* way to programatically obtain a unique ID for a Netduino to use as an ID in the web services?
If not, we are thinking of a few other ways to do this ... but I was hoping there could be something?

I'm sure Chris has better/different ways, but what but about using the MAC address? If your using the Netduino plus you can write a unique ID to an SD card and store it on there. Depending on your timeline, I believe the ability to read/write a small amount of data to the on-board EEPROM is coming in NETMF 4.2.

I'm not planning on using the NetDuino Plus since we're adding our own RF modules to the serial ports of the NetDuino ... but you just gave me an idea ... I'm wondering if I can query a unique ID from the RF module!
If Chris has any other ideas ... that would be great!

Another option I just thought of is using one of the many I2C EEPROM chips? Sparkfun has them for $1.95 each.

What is cool is that the Wifi module that I am using not only has a MAC Address, but it also has a configurable ID that I can set and save in it's eeprom config. So I think that I have it solved! :-)
