Hey,
 
First of all I want to say Hi! I read a lot this forum but I've never posted topic/post before!
 
I'm looking for a hint to get started with my project. 
I have one device which is reading data from SD card. I'm unable to control it remotelly in any way - I can "control" this device only by saving new data on this SD card. I need to do it manually - so if I want to change some data on 10 devices, I need to take out 10 sd card, send new data, and put it back to devices.
 
1) I wonder if I can pretend SD card using netduino
Instead of reading data from SD card, this device would read data directly from netduino. Netduino I can control easly.
 
2) Second solution is to share one SD card by two devices. Netduino will be sending data to SD card and the other device will be reading data.
 
But I want to change data in each 10-15 seconds so It can be problematic for sharing one SD card.
 
Do you have any ideas how to solve this problem? Is it even possible?
