communication b/w microcontrollers
RS485 is great for long distance communication. You will have to devise a serial protocol of your own to use multi-master functionality, or have it master/slave driven (modbus RTU...

EEPROM strategies?
If the cell is writing while you lose power, then yes, especially when your data is multibyte.

file system based API function calls for MCU
There are optimizations done for a limited number of timing critical components, where the actual latency is not much higher than an interrupt + function pointer call (on a CPU...

Can a USB device without VID and PID be used?
Ideally you use the VID and PID of an existing device which your OS understands. The common case for USB AVRs is to use the Atmel VID&PID, which is ok for development purposes...

file system based API function calls for MCU
As someone who maintains and ports between various processors for a large code base at work, HALs are really not out of the question for many applications. You could consider our...

USB Master
The MegaU series is "brand new", so not easy to find. However, the AT90USB1287 is capable of this, combined with LUFA.

sound chip / text-to-speech for robot
You can always try sourcing the TTS IC from the SpeakAndSpell. TI might still have it listed on their page even. :)

The xMEGA 24/32 bit pointer question
If you need someone to do testing for any patches, let me know when there is something available. I haven't done any GCC hacking in years, so I'm less useful there.

xmega - sample I/O pin at 74Mhz?
At the data rate you want, its not possible directly. As I said before, you can use a FIFO, or even a serial in parallel out single byte registers. Your clock will come from a...
