Not a use case I am quick to defend, but it is worth mentioning that
this appears to be how Windows Server 2008/IIS 7 "clusters" work. The
servers in the cluster reply to ARP queries for the "shared IP" with a
MAC address that is never used to originate traffic - thus causing
traffic to the shared IP to be broadcast to all hosts in the collision
domain because it is never added to layer 2 MAC tables.
