The amateur radio community has been using realtime GPS coordinates in wireless transmissions for years now. Its called APRS and its on many platforms (I don't know if its available for Linux yet), including the PalmPilot. Kenwood now has a handheld tranceiver that has APRS capability built in. Just plug in your GPS, and away you go. As for video, just use Amateur Television. For digital stills you can use SSTV. Want to see what direction a camera is pointed? Just use an electronic compass, and configure your handheld computer to send the information as a directional vector. Want to send a short text message to the camera operator? Simply use APRS to send a short text message. This system is bidirectional in respects to its data path. APRS can be adapted for any wireless communication path (IE Cellphone, Commercial Radio, Amateur Radio, and Satellite). for more info checkout www.tapr.org. What? You're not an Ham Radio Operator? go to http://www.arrl.org for more info. My point being - don't let the marketing blitz lead you to think this is NEW technology, and it definately can be done for less than US$30,000! - Tallyman
