It sounds to me like you would probably have to write a stand-alone application
that joined the multicast and made a normal tcp or udp unicast connection to your
unicast target(s), and bridged the packets in software.

It probably wouldn't be hard to do that translation like that.

I don't think it would be easy to add that functionality directly
into xorp though.
