A few weeks ago Ogle Earth linked to APRSKML, which converts amateur radio positioning data into a KML network link for Google Earth. In the meantime, instructions for its use have been fleshed out, and now new geoblogger Ian Turton reports back on some interesting uses for it:

The best bit is that the packets can be picked up and forwarded over the internet for people to view, map and otherwise play with. For example I spent this afternoon watching a tourist light airplane trip over the Florida Keys.

Ian’s considering incorporating APRSKML into a GeoRSS server, which would automate this functionality (if I understand him right:-).
