Joe,
My original use case was for SCHC as an IP Protocol Number with diet-esp
being the sample. WIthout this we have to do a hack on the SPI management.
My more recent work definitely benefits from SCHC as an Ethertype.
My text does/will cover these use cases for why.
SCHC as a port number was added by others, primarily Pacal Thubert for
UDP firewall traversal. He will be providing the text for that use case.
Back to writing on this bumpy train ride...

I am in the process of reving draft

and adding support for schc as an ethertype and tcp/udp port number
as I said I would do back in Nov. Sigh.
I understand maybe Ethertype (though I think this is the mistake that
IPv6 made all over again), but for this to get a port number it would
need to be associated with a transport service, not just a packet type.
Why would that be needed, e.g., vs. running this inside one of any of
the numerous transport tunneling protocols (esp GRE)?
