I've often wished for something like this when helping someone learn remotely. For example, let's say I'm hanging out in #ruby-lang (IRC) and someone posts a Gist they need help with. Forking and editing their Gist works great, but there is real power in watching someone make changes to code piece-by-piece.

I voted for OpenSource, but only because I think this is the kind of tool that can thrive in an OSS environment. I wouldn't let that stop you from setting up a service as well.

Totally agree! Coming from a design background, being able to immerse myself in code and watch better-abled people code around me (and fix my code) is incredibly useful. Looking at it as a platform for education is a great idea. Codecademy + realtime!

I think open sourcing is a must: more things should be real-time! And if enough people see value in building a service around it, then shucks, we (or someone else) should do that too. :D
