Do the internals of TCP change when it's running over IPv4 vs IPv6?
Does the interface to upper layers change?
Actually, yes - the pseudoheader over which the checksum is computed
channges. So too does ICMP signalling, setting of the DF bit for
fragmentation discovery (clearing it doesn't have the same effect
in v6
as in v4), etc.

Yes - I thought that's where they were going with the SCTP stuff.
Right. But are there more general 'HTTP over transport X' rules or
conventions that need to be described?
