A similar site I built (http://stoodle.org) supports free group voice conferencing through Twilio.

Looking at all the feature requests here I can't help but think that you guys are reinventing TeamSpeak. The only difference I see is that with TeamSpeak you first must install a client whereas this runs in a browser.

Actually, there are lots of other online whiteboards that have all of these features without requiring a download or plugin.

It's easy to add audio via skype/facetime/you-name-it though.

Really? I don't think running another app to get audio is a very user friendly solution, and you'll never be able to record a session. How about Opus and webRTC or similar?

Its critical to integrate all this - else every meeting begins with a struggle to get on the same page with every app and every participant.

I think it's better standalone. I already have a hundred ways to voice chat.

That's the problem - are they the same ways everyone in your meeting uses? How much time is wasted on each 'conference call' working out who's there, who has the number, where's Bob!
