We provide an Operational Transformation Engine at www.beweevee.com that works in web applications through either a Silverlight/Javascript bridge or natively. As an example, a client of ours has integrated their javascript text editing control using Silverlight only for OT transformation purposes as their backend was entirely coded in Java. You can get more info at www.beweevee.com

Awesome, I hadn't heard of that. Thanks!

I used APE and a heavily modified tiddlywiki to put together BlipWiki at http://www.baggr.com and used the python/javascript diff-match-patch libraries from http://code.google.com/p/google-diff-match-patch/ to keep the data in sync

On the adobe side (i know) you have http://labs.adobe.com/technologies/afcs/ AFCS which answer this set of problem quite well.

As mahmud said "rest is just a simple matter of user authentication, managing timestamps, and maintaining consistency between the server side data-structure modeling the shared "object" being collaberated on,"

Which is imho not so easy.
