I have done something very similar to this, binding a process to a loopback interface/IP
and using the anycast IP method with OSPF and OLSR to export that route to that interface.

Its how I currently have multiple DNS servers to offer redundancy on my network, where the
client queries the 'local' DNS server. Local often means closest by hop count or by

I also have other services that I run only on loopback interfaces, primarily so those
services and IPs can be moved to another physical server and the whole config remains
