Most of the products for wireless ethernet these days come with a proprietary card (like SOHOware). What we need is the ability to transmit and recieve using some kind of little antenna that is in the car somewhere. Basically, we'd need an ethernet cable with a powered (or non-powered I guess) antenna on it to put in the car. This would hook into the Mk.2 unit. Then, you'd need something like this on the PC side inside the house to transmit.

So where can we round up something like this. Ideas?
