Creator of http://www.sharelatex.com here. LaTeX collaboration and environment setup is a big problem, online collaborative environments are going to become more popular. The more of them out there the better so good luck to jdleesmiller and writeLaTeX.
writeLaTeX has a nice split view which I have not implemented yet. The rate of update from collaborators seems to be relatively slow (compared to sharelatex). I would be interested in knowing the architecture behind the scenes.
Thanks for the feedback! Sharelatex is also really cool.
I'll hopefully write a blog post about the infrastructure one day, but it's actually pretty standard: a rails app on Heroku + some render machines. I'm pleased to see that it has (so far) scaled as intended!
