Is it possible to use the wired network within our house to 'extend' the controllers for our PS2?

What I'd like to do is house the game console in our 'media cupboard' plugged into the network switch and receiver/tv and plug the (suitably re-terminated) controllers into the RJ-45 wall plates beside the couch...clean, tidy and as missus friendly as I can make it.

I believe there are 9 conductors in the controller cable, but one of them is not connected, so Cat5e should provide enough wires. What are the signal levels/format. Would there need to be a balun or something?

Anyone done it, or have some good gen?

Thanks very much.
