I worked on a UML/Business Process editor for Google Wave. Apart from the tool (http://www.processwave.org/2010/05/processwaveorg-editor.html http://www.processwave.org/2010/05/processwaveorg-editor.htm...) we used Wave for all kinds of project planning and internal collaboration: Meeting minutes, decision processes, SCRUM diary, travel planning, dividing costs of lunches. We played with the document sharing feature, but finding Waves worked so badly that we never found what we were looking for. For all kinds of project documentation and notes it rocked though. We all worked in the same room, but our supervisors were a few rooms away and often commented on stuff inside Wave and started discussions (we had inside Wave). I would use Wave as a more flexible wiki replacement today, focussing on team-internal collaboration and documentation of decisions and technical things. edit: wrong link
