Yep, cleared all my cookies and it appears that things work as they should. I haven’t pored over the source too considerably but from what I saw it looks like there are very few dependencies, which makes sense as I’m guessing WP wants you to be able to integrate sign on systems without jumping through hoops.

My sites aren’t “deeply” integrated, so it would be great to get some feedback from anyone who tries this on a deep integration.

In retrospect I shouldn’t have put this at v1.0, but I expect its useful life might be short anyway once bbPress 1.0 is released…
