These guys have an open source plugin that allows IE to join the webRTC party.
This library they also have makes WebRTC cross browser compatible.
And some corporate networks are too restrictive to be pierced by STUN, which means you need a TURN server, which is a relay server.
But yes, 98% of the time, WebRTC can go directly browser to browser. As long as neither browser is Internet Explorer. Sigh.
