That would be a possible extension, if data is to be passed
through some central server (which is probably necessary, since
telcos usually don't allow direct IP traffic between mobile
terminals).

However, I think the best approach to tackle all this is to go
incrementally. A standalone trail application should already be
useful. Next, one could add simple waypoints. A camera would
actually be kinda useful ;-)

Trails of multiple users, shared in real time, would be the
"killer application". I don't think anyone is doing that at the
moment. A typical scenario would be to meet someone in a city
both don't know. Street names aren't very useful, but knowing
roughly where the other person is at the moment, would be.

Directing a taxi to the other person's location should be fun,
though ;-)
