It sounds like http://www.scribtex.com/ could be exactly what you are looking for. It's an online LaTeX editor that allows direct rendering to PDF along with most of LaTeX's other nice features. It allows for collaborative editing and it's pretty easy to share documents with other users. It's also revision controlled with the ability to revert to previous versions, although not quite as powerfully as svn or git, etc.
