I've been trying to find just the right message body to quote for a few thoughts on this thread, but can't quite find a match so... For mobile user-centric GPS activities, how about piggy-backing GPS coordinates off one of these "Instant Messager" clients/protocols? If not the client/protocol itself, how about something like that Napster-style file sharing app (can't remember the name) that hangs off the AOL client? Bonus with this technique is more flexibility in terms of authentication and encryption of the information. It's a little more scalable; you could grant access to different resolutions of position data, maybe encrypt only the smaller differential position data.
