Doing AV right is hard! You can devote your whole career to learning how to do AV well, and I have a ton of respect for the skills of the people that choose this path. It's a lot more than plugging in a microphone.
We do try to improve AV with every Devshop, and we have recently started to bring in AV professionals to help. But honestly, pre-1.0, I think it's way more appropriate for us to be spending our time and money on advancing the framework than on super slick video presentations. In many ways it's more like the Meteor community's time and money.
