(This mail is not addressed to Matthew really, it is more for the entire 
list - and it is my personal reflection)

 From my perspective, we have been working towards one target for a long 
time (and as mentioned we had a poll last year that confirmed that), and 
it has not been that controversial. Sure, not everyone likes everything 
about the API - I'm pretty sure that no-one likes every aspect of it (I 
for one have some issues) - but that is what you often get out of a 
community effort.

There are also implementations of the to-be standard available. They are 
not behaving exactly the same - but that is to be expected with early 
implementations of something that is not yet specced up. And in addition 
there are apps using those implementations.

For the last month or so there has been a lot of traffic expressing 
dislike, and the need for a re-design. I think that the responsible 
thing to do in that situation is to understand more on why, and how 
things should be changed to be better. To throw everything out and start 
from scratch would not be fair to those who have implementations or to 
those using the implementations.

And, am I the only one fearing that starting over could take a long long 
time? A lot of people think the current API is really bad, but that does 
not mean that it will be easy to agree on what a good API should look like.

So the chairs have asked for use-cases that motivate changes. We've 
asked for API methods in addition the the current ones that there is 
need for. And we have invited to a discussion on v2 of the API, but 
proposed to start from use-cases. I don't think that is unreasonable, 
but also hear that use-cases is not the right starting point.

If you have ideas or proposals (being API issues, API proposals, 
procedures, use-cases, etc.), please submit them to the list (regardless 
of if they are for v1, v2 or vN) - I'm pretty sure that good ideas will 
be picked up. Perhaps someone has a really clever idea on a mod of the 
current API that would be seen as an improvement by most?

I fully agree to Matthew that currently there is not enough detail to 
build interoperable implementations in the combined (over W3C and IETF) 
set of documents, in particular SDP details are still lacking. That must 
of course be addressed.
