AVRDUDE can program through the JTAG ICEs and AVR Dragon, and AVaRICE
can serve as a glue between the ICEs and AVR-GDB.  The latter doesn't
work too well, but it's usable.

Keep in mind that this is a clone of the fairly old first version of
the Atmel JTAG ICE.  The list of AVRs supported by that device is
quite limited.  The (fairly expensive) JTAG ICE mkII is the up-to-date
solution, and the AVR Dragon is the smaller sibling that has an
artificial limit of devices up to 32 KiB of ROM for debugging (but
nevertheless, it can /program/ all 8-bit AVRs through JTAG).
