New Dayz Server -
I like the idea of it, but the range concerns me a bit. Unless there was serious up-take, the usefulness would be next to none once you move more than say 50 meters away. So if you lose something out and about you are stuffed unless someone else has the same device.

The community part of it is very good, but I would want to know how secure it is, as if it were hacked and turned on without permission - its a beacon for a burglar.
