My first thought was that this would/could compound arp issues, but after extended pondering, I don't believe that it will cause any more problems than those that may have already existed.  I'm pretty sure that heartbeat wouldn't have any problem switching this over, but what happens on the ethernet switch when only 1 service fails over and the gratuitous arp is sent out?  Will the switch clear all the entries for the MAC's involved?
