A JTAG interface will be what you need if you are using the ATmega16,
ATmega32, ATmega162 or another STK500-compatible MCU that has On-Chip Debug
via a JTAG port.

Here is some information about using a JTAG interface with the STK500:

Most of this applies to the Atmel JTAG ICE and other "clone" JTAG
interfaces.  Because of shipping delay, duty and tax you might be better off
with a local clone than ordering an AVR ICE-Cube from the USA.  I don't know
where else you can get the adapters, but you can make one up yourself quite
easily.

If you are not using one of these MCUs, the JTAG interface won't help.  A
better place to take this discussion might be avr-chat.
