Vlad Rose :
To those who have tried this: Does this just work for Steam specific games, or will non-steam games added to the client work as well? Also, do you log into both machines with the same Steam account?
Non steam games are not officially supported, but many should work. Any game that needs elevated permissions(looking at all those "free" mmo). would need Steam to run as admin to even have a chance.
I streamed my desktop for the hell of it. Not that great but it worked.
Yes, you login to steam with your account on both systems.
If you have an Intel SB or newer cpu, you can use quick sync(to do the encoding) if you have a monitor or fake monitor connected to the onboard video as well.
EDIT.
Also for the time it is limited to 2 channel audio but the down-mix works properly.
