If somebody is interested, I wrote an extension for embedding (the upcoming)
Google waves in MediaWiki as a tag extension:
http://www.mediawiki.org/wiki/Extension:GoogleWave
If someone has a wave developer sandbox account I'd be glad if that person would
help me test the extension a bit more than I'm able to do by my self. A preview
of the extension is avalible at
http://mickenordin.se/wiki/Wave for now (I know,
my wiki looks more like WordPress than MediaWiki :)).
If nothing shows up try this:
