The API supports streams with the use of cmsghdr's. Use the
SCTP_INITMSG option (Section 7.1.4) to request more than one stream at
startup. Use the SCTP_SNDRCV (Section 5.2.2) ancillary data to
specify the stream for each datagram.

It is our intent to recommend wrapper functions ala the IPv6 Advanced
API so that you don't have to populate these data structures by hand,
but we have not specified these yet. If you have suggestions, we are
certainly interested.

Lack of stability is a short-term problem for our implementation--we
are actively developing.

Another implementation that will be out shortly is a FreeBSD
implementation from Randy Stewart. He has a very clever hack that
lets him embed the user space implementation into the kernel. Very
slick!
