I can program in VB due to its simplicity.
I love the concept of a carputer, so many apps. In my mind i see uses for team departments, so say your a strike team of fire trucks, each with a carputer and gps. You could have a big mesh network, sync gps track and routing points from the lead vehicle, and all know exactally where you are going and how to get there. Also sync up maps, mission documents, etc in one go, so everyone has the same information available.
A comms system to send data over a radio, instead of voice, so non urgent messages (all yes / no) etc could be sent and recieved over radio, preventing cross over, each message timestamped, so even if late it still enters the time it was sent.
So many ideas, looking forward to having a play and seeing different bits and peices, in my mind i sort of see a serverless Peer to Peer system running, for file transfers, VOIP between trucks if needed, Chat, all that stuff. And with brilliant plugins, could even have interfaces with engines to give the fire dept mechanics truck information before they come out for repairs.
