Should we put the SCTP max message size in the SDP?

This is probably going to sound strange coming from me, but I think it
might be a better idea to put the SCTP max message size in the SDP.

I'm still OK with having an in-band message (as we discussed during TPAC)
to swap the SCTP max message between endpoints, but I was thinking about it
a little more and realized that it does involve some extra edge cases and a
bit of possible latency.  It would be nice if we could do a handshake
earlier on.... and then I realized we can because we can just put it in the
SDP where we already do a handshake well ahead of time.

Something like:

a=sctpmap:5000 max-message-size 1000000


Obviously I'm not a big fan of stuffing lots of stuff into SDP, but I think
this is very minimal and is a more simple solution.




What do you think?
