Sadly, the Bluetooth serial port adapters all seem to require 45 mA to 
50 mA -- I checked several manufacturers.  OK for the shack, not so good 
for PDA or field use :-(  OTOH, there are tons of USB Bluetooth dongles 
that sell for under $20 -- even without rebates! :-)

Zigbee may be better for current consumption...

RFM modules, which don't have protocol stacks and error correction, 
have the advantage of needing very tiny currents.  Hmmm, maybe a 6-pin 
PIC plus an RFM module and we'd be able to create a transsparent, 
low-current, reasonable performance wireless link...
