It is not arcane nor does it require $$s.

http://www.policyrouting.org/PolicyRoutingBook/ONLINE/TOC.html

and check out Chapter 7. There is some information on getting simple
RIP/OSPF going. Also see both the Zebra and Bird projects along with the
venerable gated.

There are several scenarios where dynroutes are useful. Most notably when
running a real VPN (consider that 2.6 wil have a fully policy routing
compliant IPSec implementation). Also when monitoring link status. Many
routing daemons notice link flaps very quickly and can send SNMPv3 traps.
