Does your board include a serial (RS232) port? Is it OK to use a 
special program on the PC to update the firmware? If so, the best way 
to do this might be with a Flash Loader (sometimes called a "boot 
loader") that is compatible with Atmel's AVR Prog utility.

If your board doesn't have a serial port, your customer will need 
some kind of special interface to re-program via ISP. This is more 
cost to you, especially when the customer looses the interface.

If you have a serial port, but don't want to make your customers use 
AVR Prog, you will need a Flash Loader that can directly read in an 
Intel Hex file sent by a terminal emulator program.
