sloan-bboard won't work with PostgreSQL at first, so I suspect it will be awhile before the majority of our folks switch to it. It shouldn't be difficult to integrate "general ratings" with any particular package, so I don't think Dean would lose much by doing for the regular bboard first.
I also suspect it will take awhile for dotLRN to settle down, and folks might want to wait until it does before porting it. Or at least they'll want to tackle those parts that *are* stable first.
