Passing SCTP through "traditional" NAT should be possible if that

Well, that's what I'm asking: can most off-the-shelf NATs deal with
SCTP? Previous answers on and off this thread indicate "no"; I'm told
that most NATs don't have SCTP support and will therefore have
problems if more than one host behind the NAT wants to use the protocol.
Best way is to avoid NAT and use IPv6 which is supported by the KEXT
and the userspace impelmentation.
I can't avoid NAT, unfortunately. I'm writing a P2P app aimed at end-
users, and it has to be able to punch through whatever Linksys /
Airlink101 / etc. box that the user bought at Fry's (or got from their
ISP). I'm lucky that most all of these seem to support UPnP, if
shakily, so I can convince them to open TCP or UDP ports for me. I
really doubt the droids who write the firmware for those have even
heard of SCTP... :-p
It sounds like SCTP would only be an option for me if it were
piggybacked atop UDP (like Bryan Ford's SST protocol is). I saw an
IETF document about this, but I don't know if it's implemented.
