I bought a pair, too, since they are cheap and have library support. I just have not even opened their wrappers yet, let alone looked at any code
too many other things going on, but I do plan to explore them.
the reason I mentioned the xbee is that its a zero effort module. if you can talk wired over ttl serial, you can then get an rf link with a pair of xbees for zero effort. that's what I really like about them and that's why they can ask so much money for what is really not all that much technology inside. its just convenient as hell to have an easy serial ttl wireless transport.
