Online lectures by successful alumni

The Idea:  A fraternity or university alumni association could leverage some of their successful alumni by asking them to give a lecture via Microsoft Live Meeting, GoTo Meeting, or similar tool.

The Possibilities:  The range of ideas could be massive, from business to government to sports.  The alumni giving the lectures would be happy to be asked to give something other than their money.  The alumni groups organizing these could require that you must be a donor to attend the meeting and use that as a way to get more people giving.
