As the post's title indicates, MSBee's source code will soon be available on CodePlex; we're just waiting on final approval of the shared source license. CodePlex is an environment for creating, hosting, and managing open and shared source projects, similar to SourceForge. CodePlex uses Team Foundation Server as a source code depot and to perform work item tracking. The CodePlex website describes all its capabilities and features.

As soon as the MSBee project has been created, I'll announce it here.
