I tried Onlive multiple time and I can play perfectly well even if I connect to a server hundred of KM away using wifi on my phone. Why can't I do the same on my own 1 gbit network at home? Yeah you won't achieve the best latency but it can't be worst than the latency to the servers of Onlive so it's more than perfect for me. The DisplayPort idea is not bad, except that my ethernet cable are already placed and my TV can't connect to a DisplayPort.
