I'm also a fan of git+text editor but I do miss the collaborative editing. In the final stage of writing a paper, I want to be able to sit on a video conference call and both people edit the document at the same time, without having to stop to push and pull every little edit. Unfortunately, it seems that most collaborative editing tools are web or work on a client-server model where only the "server" has the actual files and can compile them to pdf. (The client can collaboratively edit raw latex but can't see the resulting pdf)
