:) Or....  They could come after you with the dreaded DMCA. You might want

I have been thinking about that. And it does scare me a bit. I'm probably
not going to delve into the .ebn files any ways. I'm much more interested
in just figuring what the 8535 does so I can write replacement firmware
which frees us from having to use Atmel's ever changing firmware/protocol.

Getting the SPI programming should be easy, but I need to research more on
how to set Vtarget, Vref, oscilator, etc and to do HV parallel
programming. Maybe I can do it without looking at Atmel's firmware.

Besides, as bonus, if we have open firmware, it will be easier and faster
to add support for new devices without waiting for atmel to update us into

:) I'm not trying to discourage you, but you might want to be a little more
:) discrete.

True, but its hard when you like to share. ;-)
