SCTP. At this point it may have critical mass of platforms we support
and thus be a viable option. That I know of the Windows options for it
are slim. There is a MacOS version from KAME, but I don't know the
licensing details. Since it doesn't ship with the OS (and in any case
where it doesn't) that's a practical consideration.
