There was some press - last year I think - about a company (can't remember the name) wanting to launch gaming through web-connected smart TVs (which would include TiVo). The idea was that there would be no need of a console at the users end as all the games would be stored on the company's servers and sent over the internet to the customer's TV. I wondered at the time if VM would pick this up.
Edit - here is the game company Onlive
