I depends on how you define the object. You can associate each session
with a transport pointer, which can be anything you like and will be
passed to push/pull functions and also a custom pointer which can be
anything you like and is available to you only.

A layer that would demultiplex the streams before should be needed.
That's correct.

Can't this be achieved by having a layer of demultiplexing before gnutls
that will use separate pull/push functions and a custom transport
pointer? That we could include in gnutls as helper functions for SCTP.
