Now when *I* suggested having a PC run server software to server the empeg to a Reciever, I was told there was no point in my idea.

I still think there would be no point in doing it that way.

The only reason I think it would be neat to see the car player work as a receiver-server is so that it could be a Poor Man's Jupiter, i.e., a server that doesn't require an always-on PC computer.
