In that context, if a process belongs to a brane then all of its sockets,

But, speaking of a topic that came up a week or two ago, what if the thing
I want to use the multiple tables for is to implement strict host behavior
on a multi-homed host? That is, suppose I am running a server application
on a host with two interfaces, and I just want the reply packets to connections
that came in one or the other of the interfaces to go back out the same
interface (say the interfaces connect to different service providers). Two
routing tables, one per interface, are required for this since the outbound
routing from the host needs to be done through a table that only has routes
pointing out the interface the packet needs to leave on.
Branes are the wrong solution for that problem.
What is better is to be able to issue an ioctl on the socket
and in that fashion specify which network interface to use
for sending out packets.
