About 52 minutes in Brion Vibber's tech talk at Google he mentions how they are planning to support OpenID within the next month. Very cool!

I'm not willing to wait 52 minutes, but... I've been doing some work on a MediaWiki recently, and I'm impressed. Integration of OpenID would give a platform for exploring some things that I'm distinctly not happy with in Flutterby's current Wiki implementation.

But I've been resisting PHP, despite Meuon's repeated attempts to suck me in to it, and for my personal playing I'm always interested in ways to not encourage monocultures. Does anyone out there have suggestions for a relatively developed Wiki engine in Perl, TurboGears or Ruby on Rails?
