I like this thought from Martin Geddes of why video conferences have never taken off:

“Without having something to gesticulate at — other participants, a diagram, the window — you’re left limp and lifeless. So perhaps there’s a Superman-style blue backdrop screen type of technology that can re-insert those elements.”

Perhaps this is a job for EyeToy hackers, or those with an iSight, Quartz Composer and a spare afternoon?
