Hi Iñaki,

I have been following the recent discussions for a while now, and think 
I understand the various stand points, including yours.

As I mentioned in my announcement, mapping SDP to Jingle's negotiation 
parameters is indeed one of the concerns we are going to look into. 
Philipp's work on his WebRTC plugin for Strophe.js [1], which uses 
Jingle signalling, has shown that it indeed takes quite some effort to 
map and mangle SDP to get things going. The spreadsheet questionnaire 
that Peter Thatcher asked people to fill in (thanks!) also has several 
comments to that effect. During our discussions on the Jingle mailing 
list and the meeting last week, more of such comments were made.

I want to stress, again, that Jingle's negotiation parameters should not 
be referred to as a flavor of SDP expressed in XML. This is misleading, 
as it is not managed by MMUSIC, and actually weakens your point of not 
wanting SDP as an API surface. I can understand that looking at the 
current specification could give that impression, though. The Jingle 
examples are currently interleaved by SDP examples to show the mapping, 
and we are looking into making the distinction clearer, maybe even as a 
document separate from this one.

PS. Yes, I messed up the subject header of the original announcement.
