I'll give building the Mega version a try, but will probably end up wait on 
flashing my deRFA until Axel sends me a known good version.

I'm using a USBtinyISP, so I'm out of luck in for JTAG for right now. I imagine 
I'll end up getting one before this project is done though.

Now that would be hysterical, especially after a couple of people at the 
conference figure it out. That would be utter mayhem, with people flashing 
other people's badges remotely. The anarchy would be brilliant.
