GitHub has at least some good ideas in this area. Code review and issue tracking are nice, but everyone seems to want something different from those systems so I'm not sure how to do that in a reasonable way. Access control would be nice for deploys I guess?

I hope that someone really does make an online IDE that means I don't have to use a local IDE anymore, but I'm not certain how feasible that is. Atom seems like a giant step in the right direction.
