From Keezer through Wall?

Has anyone ever put a keezer or kegerator behind a wall (e.g. closet or something) and then run lines from kegs in there through a wall into a room?

So, for example, lets say you have a rec room and you want to have taps coming out of a wall behind a bar, but no room for the kegs under the bar. But there's a closet or something in a room right behind the bar wall.

Could you run the lines from the keezer or kegerator through the wall? If so, how to you deal with keeping the lines cool.

If anyone's done this or seen a thread on anything like this here, I'd much appreciate it if you could point me to the thread.

Thanks!
