The only issue with this is that the Linux box is not acting as a router, but as the egress devices.  I'm trying to 
figure out how to properly get my application to 'color' the traffic.  standard BSD sockets appear to have no concept 
of 'Labels'.  Still seeing what I can do to match the traffic.  I am probably going to see if I can work out a hack 
with the development team to use DSCP values to tag the traffic and then act accordingly on the ingress router.  I 
appreciate all the ideas presented so far.

You could also have a look at linux namespaces if you want to manage
routing tables per process. Especially the new setns syscall could be
handy: <https://lwn.net/Articles/407495/>
