yeah, basically he is.
There's streammygame.com that's "suppose" to do this, but its an antiquated program now that hasn't been updated for a long time (website hasn't been updated since 2009) and the dude that's suppose to support it hasn't been on the site in like a year. Of what others have said, it worked flawlessly, but a pain to setup. I could never get it to work and I haven't found a good alternative. I tried again last night on my win7 machines and still couldn't get the damn permissions to work.
Most other VNC are great for remote desktop, but suck at even light duties of video play back. I remembering finding another VNC program that actually did alright with streaming small video (SD res) with audio, but not sure about gaming. The makers claim that it ws devloped for streaming games, movies and music. Its called IgRemote. (c.net download link
) I'll probably try it out after a friend told me about it, but I kinda doubt its lag-free ability for gaming.
