There have been developments in the bbPress Trac in recent days, the plugin branch is now there (but of course not ready for use). JJJ and PeteMall have been working on it. And what more, I received my first props for the plugin :P.
Another thing is that now I would be rarely updating/adding plugins for standalone version (v1.1 or below) as it would be waste of time, instead I would spend my time on improving the bbPress plugin (v1.2 and above).
There are also some heated discussions going on in the bbPress forums about having another name for the plugin or having its version number as 2.0.
