For a university project course, a friend and I did something similar, except with sound. It seems the professor posted our demonstration but not our report or code (I'll have to ask him about posting that too!): <a href="http://esg.uwaterloo.ca/node/254" rel="nofollow">http://esg.uwaterloo.ca/node/254</a>
Note to self: HP (OVIS-2) and IBM (Watson) are working on "intelligent" load balancing tools; is real-time cluster analysis possible? single-linkage (MST cluster cut)? would that be useful? balancing physical nodes with virtual, seems like some sort of optimization?
