However, I would really like to reinforce the point from another note.
There are quite a few contexts where the ability to run a sensible
transport directly over IP is indeed very useful. For example, the
ForCES working group scope is limited (by chart) to the case where the
control element is near the forwarding element. I am not worried about
there being a NAT between those. So SCTP or DCCP over IP is very relevant.
Yours,

I wrote this because of a discussion that happened during behave at the
last IETF meeting in Vancouver. There was a presentation in the behave
working group on NAT ALG for SCTP - when run natively over IP - and I
found the entire conversation surreal. The entire problem would have
been moot if SCTP had been designed to run over UDP and not IP.
So apparently its not obvious to everyone that you cannot design
protocols natively ontop of IP.
