Axel,

Thanks for the info. I tried loading the bootloader from within the Arduino UI 
and it wasn't happy, as avrdude is complaining about the address being out of 
range.

avrdude: reading input file "ATmegaBOOT_radiofaro.hex"
avrdude: input file ATmegaBOOT_radiofaro.hex auto detected as Intel Hex
avrdude: ERROR: address 0x10f010 out of range at line 2 of 
ATmegaBOOT_radiofaro.hex
avrdude: write to file 'ATmegaBOOT_radiofaro.hex' failed

I also keep getting this warning about efuse:

avrdude: safemode: efuse changed! Was ff, and is now f7
Would you like this fuse to be changed back? [y/n] y
avrdude: safemode: and is now rescued
avrdude: safemode: Fuses OK

For antennae on the badges, we'll probably do the same thing we did last year 
and build a PCB trace antenna into the board to keep costs down. Every dollar 
counts when you're doing a con on the cheap, and each chip antenna is a dollar 
or so.
