Just use some low-latency virtual desktop, and you can stream games from Your own home machine For sake of fun and experiment, I've once tried Witcher 2 on N900 via VNC, configured for as low latency as it's possible - and, surprisingly, it was *almost* playable - not problem with traveling, conversing, using items etc, only fight was obviously little too slow.

Of course, VNC *is not* low latency virtual desktop, so people with enough knowledge and motivation, can try this

// Edit

In case someone haven't noticed, low-latency virtual desktop is almost literally what onlive does. It just use proprietary virtual desktop software and servers (limited to allow using of games per-installed on their HD's, obviously), and request you to pay them for using their non-Open solution
