I know the original JTAG claimed you couldn't have anything other than the AVR 
in the chain. I seem to recall something about it now being possible but the 
AVR has to be the first device?

You're best bet is to check the help in AVRStudio, which is the latest source 
of info on the tools (JTAG and JTAG MK2).

A DataFLASH is pretty cheap, and in some applications it allows you to do even 
more. For instance have multiple AVR or FPGA configurations you can switch 
between...

Again the lubloader (newae.com/loonboard/lubloader) is an open-source example 
of doing that (with docs!).
