AVR-Chat

Or...

   Check out an Arduino install and look at the bootloader source in 
there.  There are options for creating the bootloader on a MEGA128 using 
one of the USARTs.  The Arduino bootloader is based upon the Atmel app 
note that makes it look like an AVR ISP (STK500).  Then you can just use 
AVRdude or your favorite programmer software and have no need for custom 
GUI code to download to your part.  In my case I'm using it in a MEGA168 
with a Sparkfun Bluetooth module for totally wireless code downloading 
through the virtual COM port on the PC.

have fun,
