I have a Hawking Wireless AP in my Dodge Ram.
The range isn't fantastic, but gives me a consistent 11M link to the office from the carpark.

I use it and the empeg to provide a streaming mp3 server at work.

I also have a hijack app that connects to our inhouse voicemail server and downloads and plays my voicemail when I pull in to the carpark. Technology for its own sake, I know, but its kinda fun to see the look on your passengers face when you pull into the car park and hear "you've got voicemail...."
