AVR-Chat

Ok thanks guys,

I too plan just to use it for internal storage - it would not be accessible
to the end user without opening the case. Download would most likely me via
USB, but it seems the the XMEGA's dont feature USB.

Perhaps I should start looking at the AVR32 as the external memory bus would
also allow the use of SRAM as an option.
