I have a HTPC (home theater pc) set up and running on my wireless network. Its a Acer Revo running the latest version of XBMC-live...which runs on ubuntu. I recently bought a new TV with a few internet-ready features, but I don't have a ethernet cable run into my living room. (it doesnt have any wireless capabilities)

Is there a way to route the wireless my HTPC is receiving to my TV?

I've tried looking for guides online, but I've only found ones to make a dedicated router, which I don't want

Any help is appreciated. Thanks!
