Your first paragraph makes valid points, but your conclusion :
-- all you have to do poll you local ARP table --
will not work if you have multiple routed subnets, because of proxy ARP.

    Good point - Though it should be easy to determine if the router is proxying arp requests (lot's of IP's with the same MAC).

    The only really reliable way of getting all MACs, I can think of would be polling SNMP enabled switches, assuming that each subnet is running switched traffic.
