Decentralized version control?

As part of our discussions, we're chatting about the possibility of the 'next gen' Subversion being a decentralized system. So, in a radical act of open-mindedness, we're actually playing around with Mercurial to get a taste of such a system. As people take notes, we're storing them in a Mercurial repository, and pushing/pulling changesets around. Info on the repository is available at this url.
