Collection of req's and design decisions relevant for protocol discussion

Hi,

as agreed in the recent phone meeting, I have extracted from the draft 
final report the requirements and design decisions that appear relevant 
for the protocol.

I have taken the liberty to group them by relevant aspects of what to me 
seem relevant aspects of the interaction between UA and SS.

Comments / improvements very welcome.

Best,
Marc

Those of us who huddled at the end of the last meeting briefly discussed using WebSockets, with the audio sent as a series of binary messages, and signaling as MIME text messages using a subset of MRCP as a starting point.  I'd already started writing some notes along these lines few weeks ago - nothing profound, but it might be a good starting point.  I'll tidy it up and send it out for discussion.  Milan, you had also mentioned you could suggest a subset of MRCP.  I think this would be useful to give us a sense of the scope of work.

No comment on the latter, but I don't envisage a big production here.  Just an exercise in diligence.  Most of the requirements have been expressed from the point of view of the UA, API or user agent, and I'm concerned that some of the protocol requirements are implied but not explicit.  Better to find those now rather than later.

There's no need to complete #2 before starting #3, although I would like to have a draft of #2 before diving into #3 so we can structure the discussion.
