What I'm implementing is, as Qing said, a form of policy based forwarding
i.e. you can use a broad set of criteria to select a "FIB" (to use the terms here) dependent on a number of criteria.
Criteria include source socket (for local connections) which
is derived from process information at socket creation time, or a
socket option. Firewalls such as pf or ipfw can also select a FIB for a particular incoming packet to be forwarded.

Thanks. This is exactly how I believe it should play out -- pf/ipfw/ipf can be used as packet classifier engines for stuff like this, as well as MPLS in future.

cheers
