I agree. We still assume too much knowledge on the network admin side.

Yes, thats one option. Even better than heartbeat and IPAT, if all your
systems support running a routing protocol.
(In essence, heartbeat & IPAT is nothing but reinventing a subset of the
functionality of a hardened routing protocol like OSPF/RIPv2/EIGRP)
