This looks interesting:
It sounds a lot like part of my idea for a QA site.
Allows bug reports, wiki documents, and commit messages to reference each other, by creating hyperlinks based on the identifiers:
So a wiki page can reference a bug report and vice versa, a commit log can reference bug numbers or requirements, etc. and it’s all recorded in a mailing list (mailman) archive.
I’d work on smoother integration, as well as integration with a task application, and tests.
