Keepalived appears to support it already, and it's required for certain cloud providers that disallow multicast.

The peer-address option doesn't work quite well in keepalived 1.2.x from jessie. VRRP transition works, but then it goes into an endless loop of sending an ARP who-has request for checking availability of the virtual address.
This issue is fixed in 1.3.5, but adopting 1.3.5 is not so easy and needs some discussion, see T616
