Ian,

     I may be botching the QUIC terminology.  Hopefully, you get the gist...     

     Is there a handshake for each stream?  I believe the selection of which FEC to use can be different for different streams.  I am thinking about a case where I would use the FEC to compensate for lost packets which are painful to recover over a long latency link (i.e. geo satellite).  But, I might not know that I am crossing such a link before I start.  I can learn from recent previous sessions.  I am wondering if I can also learn from streams which were started earlier in the current session.

     A related thought is can the amount of repair being sent vary based on the learned RTT?

John
