Re: [Moq] Agenda topics for side meeting on Tuesday

Hi,

I've looked at the following uses cases fairly closely for QUIC in the past.

   - Live Video Ingestion - Existing protocols don't fully meet our needs
   (ie: performance vs reliability, standardization, etc), and this is
   becoming a real problem.
   - Live Video Delivery - Currently we're pushing the edge of what HTTP
   can do efficiently, including some non-standard extensions.  This is also
   not optimized for QUIC or HTTP/3, which could improve performance.
   - WebRTC over QUIC, ie: RTP over QUIC + Datachannels over QUIC - There
   could be a number of benefits of WebRTC over QUIC.  A number of people who
   were interested in this are now focused on WebTransport, but there's still
   the matter of what you send over WebTransport, so I think there's some work
   to be done in addition to finishing WebTransport.

As with QUIC, I see we have a number of different working groups different
parts or applications could land in.  I worry that could cause
fragmentation if each sub-domain solves their problem without collaborating
closely with others.  I'm not sure if a new WG(ie: QUIC-style) is necessary
here, but I do think caution should be taken to ensure we don't reinvent
the wheel 3+ different ways.

Thanks, Ian
