Interesting game concept. (GPS's and Paintball)

Flip-side...

Here's how I would do it:

The Caches would be drop boxes (already used by most promoters like MXS, Viper...) and be hidden on the field by the promoter, quite a few are spread out on the field. The drop boxes are locked and need to be opened at your base, your base ref has the keys. Each team is given GPS co-ordinates for 3 boxes, possibly some the same box. Within the boxes are co-ordinates for other boxes, each box is numberd and called in to the promoter when retrieved gaining the team points.
This could be intergrated into the standard Role-playing format as another set of missions. The boxes would need to be well hidden but with the amount of "run & gun" types that attend events, the possibility of stumbling onto a drop box would be possible. It would take a bit of planning on what co-ordinates are given out and which need to be gained from retreavals, but I think it would add a fun twist to any event.

As far as having GPS units, I guess a rental option would be nice but it's not like every player would need to have one. A few mission oriented teams with 1 GPS per team would do. :)

Only thing that would be hard to come up with are some good topo maps. But I understand these can be ordered offline now so maybe even that can be easy depending upon your location.

You can download and print 1:24,000 maps at http://www.lostoutdoors.com/newmap.html They would not be as good as a purchased paper map from USGS for $5 each, but they are free:)

I have the National Geographic TOPO! State maps for a few states around me. These puppies are $99 each (usually for each state), but well worth it.

Some of this has been done

In a few scenarios the GPS stuff has been done, sometimes by the players. In one case a spy on a scenario team was carrying a transmitting GPS radio and went on all the missions. This told the other team in real time where the enemy missions were going.
