This post got me thinking about on-line code review with people you may not necessarily be directly involved with. For distributed programming, there are tools like Bugzilla and Bonsai which can build a good working environment, but what about tools directly related to facilitating refactoring and feedback?

You could use a "bulletin-board" type tool to do this, mayb e with some modifications. Under an XP-type environment, you are going to want to review changes, and refactorings, to make sure they are better and more robust.

Are there any tools which can help support code review that are readily available?
