Wiki recommendations -- Practical Experience

[Xander Pirdy]

I am sure that in your reading you have come accross wikimatrix 
(http://www.wikimatrix.org/), which allows you to examine multiple wiki's 
concurrently, as well as provides a selector program (though it isn't 
perfect) that may aide in your search.

I also thought that I may mention using google 
wave(http://code.google.com/p/wave-protocol/wiki/Installation) for what 
you want to do. It has many many add ons, is open source and somewhat bridges
the gap between email and wiki's imho.

I would also recomend once you narrow it down to just try them out and get 
feedback from the users. I personally use hatta-wiki, and love it, but I 
don't think that it would meet all of your requirements.

And please do post back what you decide, because I am currious as well.
