How can I broadcast my desktop (like Windows Remote Desktop, VNC, etc.) while I'm playing a game, with enough speed that my gameplay will be somewhat smooth? Can anyone recommend some other software (Mac OS, Linux)?
VNC framerate is just a little low. I can understand someone will say that the latency is just too high, but with a service like OnLive (http://onlive.com) which is over the internet, I have a hard time believing that my local network is too slow to handle it.

If you want to broadcast your game play over the internet, take a look at Justin.tv (http://www.justin.tv). Unfortunately I haven't hosted any live gaming sessions on it, but I watch a lot of games using the site. The game play appears smooth and does not display any lag. This video shows how to set up your computer for broadcasting WoW.
A lot of people use it so I think it would be a good choice. If you only want to share your desktop on a LAN, this might not be suitable.
