Turns out a lot of different types of devices have taken advantage of this class to provide simple file-like cross-platform access to device internal memory. I think this is a very interesting idea, and worth a close look. Wikipedia has a good overview, and points to an article and book by Jan Axelson that covers basically everything. Added to my Amazon buy list! Here is a chip-based FAT16 file system. Now if it would only provide a USB client interface as well…

This is pretty much the simplest way to use the Xbee modules. Also, here is a breakout board for Xbee modules from the good people at SparkFun. Finally, here is a USB board for the same modules.
