We've added Google Wave to our capabilities.  Right now super secret Study Group discussions are being done using Google Wave.  So far Wave is proving to be useful.  It's pretty simple.  It just allows for two or more people to explore topics and ideas in a very straight forward conversational mode, very much like email.  Then Wave adds the ability to easily split off just one topic and continue to explore that.  Unlike email everything is editable, so you can actually go back and make changes to clarify or modify content.  At the end you have a fairly good recording of how the conversation developed and flowed.  Something that new participants should be able to follow no matter when they join the conversation.
