Ham Radio enthusiasts have been enjoying wireless "BBS's" for a while now in the form of packet radio. Packet radio is essentially a DTMF modem that hooks up to your ham radio, allowing you to transmit data packets usually around 9600 bps, sometimes 19200.

See if you can find out what kind of BBS options packet radio enthusiasts have, and what kind of local-oriented things they can do with their network.
