It is. In case someone wants to buy genuine Atmel,
note that there is a new version: AVR JTAGICE MK-II.

There had been plans more than once, but the whole
GCC/GDB debugging is still all Greek to me. I'll
have a look into avrmon. At least I have something
to start with now.
IMHO, GPL is no problem in this case. Recently I
checked in the new nutconf code, which is released
under GPL as well. As long as the code will not
be part of the final product, GPL is acceptable I
think. Any other views?
