Video conferencing is a problem that cannot be solved with software alone. I like to call it the 'last meter problem', as video conference issues are almost always caused by crappy consumer grade equipment.

Wireless routers are the biggest culprit. Convince people to use a wired connection and be amazed how much better video conferencing suddenly becomes.

It's probably a software problem at heart though, if you include firmware level. Since VGA-connectors went out of fashion I'm still to use a projector that Just Works without having to use it 10 times before figuring out all its quirks.
