I have made my specific objections to PeerConnection on this list, and 
I'm awaiting some feedback from Ian and others on those before making 
any more specific proposals for changes to PeerConnection.

My work was started before the revised PeerConnection API came out, and 
I discussed the proposal with Ian before he published PeerConnection, so 
I felt that it was fairer to publish both proposals at this time than to 
bury the fact that I had been working on something else.

I'm very much in favour of ending up with one API for the management of 
real-time connections between browsers. As I wrote in my first message 
on the thread, I do not favor embedding this API in the HTML5 tome, but 
am willing to live with that if the community decides that this is the 
proper path forward.

The second one also lacks the possibility to send text peer-to-peer, something that can be very important for certain cases (e.g. gaming).
