This is a very very good thing. Rather than distract Juxo from his very important talks with Brion, friendly trolls will stand by to help in any way they want. For instance can we create a wiki software needs page where we can set this up and perhaps look at how other wikis like tikiwiki and MoinMoinWiki might do this, to find ways to support it in mediawiki? Also see m:wikitext standard which would really help a lot perhaps...
