Just a cursory question, but would it be possible to just use iptables

The the application could manage the priorities by opening two different
sockets (bound to different IP addresses) and do the scheduling there?

That's how I would attempt to implement this.  I really don't like this
idea of putting a pseudo-classifier in the accept queue logic, and an
ugly GLOBAL one at that, if anything it ought to be per-socket but even
that I don't like.
