IMHO, it is always a good idea to have completely different infrastructure
supporting Oob. It is the only way you can recover remotely from many types
of network errors. If the router is hung at rommon, somebody has to get on
console .... or accidentally removes your igp instanance ...

But, the business criticality of the network needs to justify the cost
(dial, DSL, 3rd party L3 vpn ....)
