Wiki docs

This is a message to begin the conversation (possibly) about the
feasibility of a documentation Wiki for the purpose of user contribution
and translations.

The wiki (which is not online yet) will be at:

http://jasonclinton.com/iip-wiki/

I have done some reseach and would like to implement a Ruby based
solution. So far I have identified two options and am examining the cost
benefit ratio. Both developer access (mostly me since I'm learning Ruby)
and user access are important to me. I will not choose a solution that is
too difficult for either.

Here is what I'm considering:
http://raa.ruby-lang.org/list.rhtml?name=rwiki

Of course, the RD format is somewhat obsure so this is a check against
this solution. In the end, I may be forced to learn Perl (yay!), after all.

Feel free to reply to this message with suggestions.
