[QUOTE=pimpJ]I still highly doubt that a <2ghz CPU could knock out all the proccessing we're discussing here. I think you'd have to have a server, of reasonable power, just to knock out all these calculations, then upload that to a site accessable from the car. QUOTE]
Well, it will/would be difficult but a sub 2 ghz proc could do it all. You may need more than one machine or set up several stations as I mentioned before w/ cheap CB Radios and have them be constant beacons then you can always triangulate your position to then then figure out how to locate to coppers and then you can actively triangulate all positons real time. Expensive,yeah. Heavy on the programming, yeah. Worth it, yeah, it'd be cool.
Another idea is that you could use known hotspots (open or encrypted) and their known gps locations as your beacons then triangulate the cops position from them.
I think the hardest part is "seeing" where the coppers are.
