For testing purposes, perhaps you could establish a VPN connection
between the two hosts (e.g. with openvpn or openswan) and configure a
private subnet over the VPN link.  That way all multicast traffic would
be tunneled over the VPN link.

Beware that if the two hosts are not in close proximity and do not have
a reliable, low-latency network connection, the cluster could perform
poorly and/or behave erratically.  In my experience, such clusters are
only as reliable as the network connecting them.  (That's to say we
learned a lot about networks before we got ours to perform reliably
well.)
