I think they've done a very excellent job with Cloud9 and I've signed up to play around with it some more.

However, the problem to me seems that in order to reap the benefits of Cloud9 one has to give up the benefits of their current IDE. It will undoubtedly be the same situation for LightTable when they release.

I want collaborative editing in my IDE. If I'm using Visual Studio and my colleague is using SublimeText, I want to be able to work collaboratively with him/her. I've wondered if some sort of protocol could be created by which other developers could create plugins for popular IDEs that might allow cross-IDE collaboration.
