As for the wireless networking built in, I expect it would be extremely unlikely as the hardware for that is a bit expensive, and there are quite a few people who wouldn't use it (for instance if you have underground parking in an apartment building). However, you can get something like Apple's Airport base station, get the power from your car and plug the ethernet cable into empeg. Shouldn't be much more to it than that from what I've seen elsewhere ;)
