I want to connect my Thinkpad tablet to my HDTV wirelessly, as it comes with Intel's WiDi. My telelvision is not a "smart" one, and I don't want to purchase an adapter if it not necessary. I do have a wireless HTPC connected to the television as well, and was wondering if there is a way to use it as an ad-hoc adapter. Or is there another (dirt cheap) solution to this that I am missing? Aside from a 20-odd foot cable connection.
