That, I believe is the solution (and probably the only solution).
Thanks! The details on this would not let you enable multicast on
R4...and this takes care of that. I'll run it in the lab. Thanks,
Chris and Petr!

NAT would appear to be a solution, meaning translate the multicast
address on R2 to the subnet broadcast address of VLAN 70 (assuming R4
allows directed broadcasts).

Maybe some more details on topology, probably we can link VLAN70 to R2
some other way...
