That will be in the next release. When *that* is due, I do not know.
I suspect that we will release a version 1.0.0 based on the latest
sctplib-1.0.0-a16, when enough people have reported that it works
as well as expected. This version then will NOT have ADD-IP
(but PR-SCTP).
A new version (now named pre20) will be released as
sctplib-1.1.0 probably some time after the next bakeoff.
Realistically, that probably means not before the end of June.

Do we ? Or does our implementation ?
NATs with multi-homing probably breaks the protocol...as a server
behind a NAT has no way of finding out, that it is behind a NAT, it
will happily send out its private adresses in the INIT-ACK. Since
that information is protected by a signature (i.e. the COOKIE),
this will not work (at least with our implementation).
A client with multi-homing will send its private addresses in the
INIT chunk. A NAT would have to replace these by its own addresses,
and that might then work. Single-homing probably works fine, as
a client will not send its address in the INIT.
If you try this out, please let us know how it worked !
Regards,
Andreas
