what I called routing a packet according to source, seems to be a well  
know (so to speak) thing: policy based routing: http://en.wikipedia.org/wiki/Policy-based_routing 
  that, apart from ipfw fwd (for ipv4) is supported (more finely) by  
linux (with some bugs) and Cisco IOS (with more than some bugs I  
suppose...)
So, since you have a cisco somewhere, go and read:
http://www.cisco.com/en/US/docs/ios/12_0/qos/configuration/guide/qcpolicy.html

towards the end there is even a specific example for "ow to route  
traffic from different sources to different places (next hops)"

Thank you for making me look for this info, as I had already to patch  
macosx ipfw (the kernel really), to make fwd functional, but with this  
I will be able to do it in the cisco router, and leave the kernel  
alone...
