Indeed - I use it like that myself. However, do both servers reply to a request from the same MAC address, when they're both functioning normally (and not in failover mode)? In my log files I'm used seeing entries indicating that *this* server just answered a DHCP request, or that the other server responded to it, and they each cache the responses, so that the same server responds to the request from the same MAC address next time around. Nice that Brian seems to have come up with a solution for the problem, though. It's nicely generic and extensible to any service check, as well.
