ThoughtWorks Studios, a software development startup, is launching a new version of its project management tool, Mingle, and is rolling out integration with Google Wave.

Users can view and interact with Mingle from within Google Wave. The partnership is an interesting play for the IT-focused enterprise, when its comes to Wave, which has been received with mixed views.
