But that's a user-land implementation. Surely the in-kernel version has to be
more similar to TCP than so? I checked out the examples in this article:

         http://www.ibm.com/developerworks/linux/library/l-sctp/

Of course, I'm quite sure it is bound to differ more between platforms than
traditional TCP/UDP do.

http://tools.ietf.org/html/draft-natarajan-http-over-sctp-01 is the draft work
for HTTP over SCTP and

http://tools.ietf.org/html/draft-wood-tae-specifying-uri-transports-06
suggests a way to specify "transport mechanisms in Uniform Resource
Identifiers".

From what I've understood, things such as Pipelining is more or less already
provided by SCTP natively. I think Mark Nottingham mentioned that in his
http://daniel.haxx.se/blog/2009/04/22/http-status-report/

As far as implementation goes, I figure a good start would be to make the
sws.c test suite server to function with SCTP and then clone set of tests to
use the http-sctp URL of choice to see how it works...
