Stefan,
I searched for a way to do this myself, couldn't find it.

Multiple linux machines, none of which are acting as a gateway between the
two said subnets? If it's a gateway machine, this would make sense (to me
at least).

rwhod sends it's packets via broadcast to the current subnet. Obviously
the machines on the 2nd subnet are unable to receive the packets. It'll
also send multicast over any available interfaces, but the ttl is set to 1,
so the only device that would receive that packet would be the device on
the far end of that interface.

It did, but no worries.
