SCTP is very telecom-shaped; in particular, IIRC, the number of streams is fixed at the start of the connection, so (this sucks but also) GP’s problem does not appear.
That problem doesn't appear, but also trying to pass off a stream as a readable/writable thing to a polymorphic interface ("everything is file") wouldn't work.
...however sctp_peeloff (see other thread) fixes the issue. Hurray!
