*Yes, the Essen implementation is a userland library.  The socket api for
it is based on the internet draft: Sockets API Extensions for Stream Control
 Transmission Protocol (SCTP),
http://tools.ietf.org/html/draft-ietf-tsvwg-sctpsocket-15

While this API is intended for use with their sctplib, it can apparently be
used
with a native OS SCTP implementation.

I'm using Suse 10.3 and I've installed lksctp.  However, Essen's version may

prove to be more portable in future.  It's still possible I might drop it in
favour
of another library.
