Can you fix this the way it is commonly done in routers?  That is,
configure a GRE tunnel as the end points to get a real-looking
interface that you can route over, do multicast, etc., and then
push the GRE packets through ipsec.  I've wondered if this would
work between a Linux box and a Cisco router but never had time to
test it.  (I have done GRE tunnels and multicast, just not the
ipsec part).
