In theory, the AirEZY ought to perform just as though you had two peer-to-peer computers hooked up together. When the car drives off, then that "terminal" isn't on the network anymore. I've got my computer and my wife's networked via 100BaseT right now. If I got an AirEZY for the car, I'd need one for my computer to do the sending. Then to keep my current wired network in place, I'd need another NIC in my computer to get to my wife's computer -- basically two little subnets.

Get it?
