I have a team site that has a blank meeting site below it.  The blank meeting site contains links to all meetings below it.  I would like a content rollup that takes all major version of documents from the meeting sites and shows them in the shared documents at the team site level.  I also want the same for contacts.  Any attendees of the meetings should rollup into project contacts.  Any action items get rolled up into project tasks.  So the team site will be able to be managed as a project site with Contacts, Team Members, Tasks can be rolled up from Meeting sites.

 Has this been done before?  Are there any web parts that can do this?
