Randall has been maintaining his SCTP stack on FreeBSD 4.x,
OpenBSD, and NetBSD. It has recently been ported to Darwin.

Interesting stuff:

There is one kernel implementation of SCTP in
the Linux 2.6 series of kernels ( http://lksctp.sourceforge.net ),
and another kernel level implementation available separately
( http://www.openss7.org/sctp.html ).
SCTP is an IETF standard, and a lot of people are getting interested
in it. It would be nice to have it in FreeBSD, especially since
it is showing up in the Linux distributions.
The only issue with Randall's implementation is that
it is only for 4.x.....I looked a while back at porting it to 5.x/CURRENT....
there is some work that needs to be done, i.e. using
the new zone(9) API for allocating memory, and probably also
getting the locking right.
I don't know how much overlap there is with what Andre is going to
implement, but I thought I would throw the information out there
for those who may be interested. :)
