I've used scannotation before, which is reasonably well known I believe, but could probably be improved on. I think with multiple versions at Apache, it is a perfect concept for commons. I would check out [discovery] first to see if that has a similar goal.
I'd set it up separately to [lang] first, to see how big it is. It feels a little frameworky, but may be suitable for inclusion. I also think that we should look to include ideas from the old [id] project into [lang], as [id] is never going to be released.
