I would like to mention that there IS a draft API,
draft-stewart-sctpsocket-sigtran-02.txt.

The proposed API provides two alternative views.

One view provides a TCP-style interface and is specifically designed
to make it easy to port TCP applications to SCTP.

The other view provides a UDP-style interface. The UDP-style
interface is designed with extremely high traffic applications in
mind. It allows a single fd for hundreds of associations, and also
allows you to peel off a single association into its own fd. It is
very similar to current UDP, but there is an extra cmsghdr structure
which carries SCTP-specific information.

Both views allow optional notifications of SCTP-related events. The
format of these events will probably change at least one more time.

If I can get the funding, I may be implementing a Java API by
mid-summer. In that case, I'm very likely to borrow heavily from
Andreas' and Michael's API. I really like the callback model, but
that is very difficult to implement at the kernel level.
