Well, if that one interests you, mine may also :) http://simpliwiki.com -- it's nodejs & open source.

http://bitemyapp.com:8000/ there's a test build of it,

https://github.com/bitemyapp/thodol

and there's the github. It's nowhere near done, and while history is being saved, I need to make a differential front-end to it.

Let me know if you want an account on the test deployment.

If people show an interest, I'll start taking suggestions on features and implement them.

I could probably get it rest of the way to 80% done in one more weekend. This was just two days of fiddling so far.
