SynchroEdit

SynchroEdit is exactly what it sounds like. Multiple users can edit the same document at the same time and all the users will be synchronized to the latest version of the edits. I could definitely see the possibilities with this fun tool although how you’re supposed to take care of the “two people edit the same thing” issue is beyond me.
Currently in alpha right now, but will be open-sourced. Definitely a worthwhile tool to keep an eye out on.
Only thing I dislike about it? Java sync server. If it runs a vm, there could be a lot of issues with vast quantities of users editing the same document. Just a thought though. Will definitely test it when it comes out of alpha.
