Replacing the Radio Modem.

[AlbertW]

There's a palm Bluetooth access point that has a range of 100 m, I assume it does this by applying more power to the transciever. ::shrug::

In my experience, WiFi and Bluetooth have never had a significant problem with eachother. We have a WiFi network at my house, and I sync with my Bluetooth cell phone nearly every day.

i like the idea of a bluetooth radio, but off the shelf bluetooth wouldn't work. they'd be worried about people with laptops taking over robots...

You can't do this. Just like you can't use your laptop to sync with someone else's phone without their consent. You have to enter an identical passcode on both sides for bluetooth to pair.
