This all sounds great 🙂
The IM-to-blog stuff should be fun. We’ve been using a similar tool (the ‘chump bot’) for a couple of years in the #rdfig IRC channel on irc.freenode.net; see http://rdfig.xmlhack.com/ for the result.
Turns out to be a really nice tool for quick’n’dirty info sharing in a small community. The reulting text is more disjointed than a traditional weblog, but the communal/commenting aspect is really nice.
And yeah it’s wonderful to hear there’s RSS support. I don’t even care which version of RSS it is 🙂
