I think it would be a killer feature if it was possible to have more than one person to look and edit online code at once.
It could be used for virtual/remote pair-programming sessions.
Where I see the problem is in supporting a test framework, especially separating test and normal code.
I guess it would force the sessions to be TDD as if you meant it, having both tests and implementation code on the same file/snippet - which for small katas it's even desirable (to keep the code small and clean)
