This is very cool. I'd love to read more about how it works. I think they're running a dedicated iOS simulator for each app and streaming the user input/video output via Flash. Even their $60/mo plan has a limit of 10 simultaneous viewers, so I imagine it's pretty taxing on their hardware.
They must be capturing the output at some deeper layer though since OpenGL doesn't render (but it does run).
Maybe, except that these demo apps, Yelp, Hipmunk, etc. are probably seeing 100s of simultaneous viewings right now. I guess they could have racks and racks of mac minis.
I'm guessing they increased the limit for the demos for free. I wouldn't be surprised if a single machine could run a dozen or two apps simultaneously, if they were able to trick the simulator into running multiple instances.
