bonjour is:

 224.0.0.251

by definition it's local to one subnet.

224.0.0.0   - 224.0.0.255     (224.0.0/24)  Local Network Control Block

http://tools.ietf.org/html/rfc3171

routers are not allowed to forward that (you don't want to forward ospf
LSAs (224.0.0.5) between subnets either).

but scalable... wide area bonjour is  not trickery, it is however a
service for which dynamic dns updates are well suited.

put the devices on the same subnet.

your multicast config looks like it would work albiet you're using pim
DM which is designed to flood everything (your goal I know).
