[e2e] overlay over TCP

[RJ Atkinson]

Perhaps one of the paths forward is for folks who propose new 
transport-layer
protocols to also have an informational document targeted at folks who 
build
firewalls (or other middle boxes) to help educate them on what the real 
risks
are (and aren't) with the new protocol and also to give them help on how
to implement support for that new protocol in their middle box...

For example, with SCTP, one of the things that could help would be 
specific
openly published information on efficiently re-calculating the SCTP 
checksum
after a NAT has done its work, for example.  Many folks know how to do 
this
with a Fletcher checksum (often because they've looked at BSDish code),
but not so many know how to do it with SCTP's new checksum.

(My assumption here is that the big barrier is confusion/ignorance. :-)
