We recorded the Code Camp 2011 SkullSpace track [1] with those firewire cameras piped into a laptop running dvswitch [2]. We had two audio streams (wireless presenter mic and camera-based 'audience' mic) and two video streams (presenter, slides). Instead of live mixing with dvswitch we just dumped the raw DV footage to some hard drives and then I edited them all together later.
It was a lot of work to get everything organized, set up, ensure it all worked and ran smoothly during the event, and then finally edit the DVs into something that wasn't crap. Not to discourage anyone, but someone just has to step up and start executing on this idea. We have the technology, we just need someone dedicated to making it happen to do it.
