Oh my, that's fabulous! Thanks so much. I knew something like that must exist, but didn't know how to search for it.

Glad to have helped :) Do try out Screenhero too, and if you have any feedback on it, please let us know [I'm one of the founders of Screenhero]!

I sure will. I actually didn't mean to be so dismissive in original post. ScreenHero seems like it was designed to solve a different problem than something like Sococo, and I can't imagine trying to pair-program when your screens are separated ;)
