I can appreciate your efforts here. It isn't trivial to put something like this together but I'm going to go ahead and state the obvious: Face to face is far superior to a solution such as this one for what I think are self evident reasons. You're better off, by orders of magnitude, getting on a plane or train and going to see your code buddies.

When I'm coding with someone we're not usually on the same files or piece of code anyway. And I don't get any value from seeing them type away at the code file that they are focused in, or knowing which file they're in beyond the name. It's a simple "hey mate what line are you on?" question.

I get excellent value from talking to and seeing the other devs face to face figuring out where their head's at and what 'page' they're on. That's the stuff of a proper realtime and face to face code sesh IMHO.
