APRS (aprs.net) is a system ham radio operators use to broadcast short text messages (sound familiar?), usually about their current position, current weather, etc.
If you "telnet rotate.aprs.net 10152" and enter "user READONLY pass -1", you can see most (all?) APRS data. I think it'd be useful to stream this data into twitter to make it more available. There's quite a bit of data generated every minute, so this might require an exception to the normal tweets-per-hour policy.
