Multicast routing between subnets? (Can it be done?)

[Numbski]

Shorthand question - can zeroconf (or rendezvous/bonjour if you prefer) be made to cross subnets?  5353 UDP sourcing to/from a 224.x.x.x address.  More info here:

I have several satellite offices I'm working with, and they're clamoring for this tech. :\

Those are broadcasts that don't leave the local subnet (think what would happen if the broadcasts would leave their subnet; poor internet!). You would have to setup some kind of central server all your clients log on to find each other. Don't know if this is possible for your application but in case the application is designed for anything larger than single LANs there should be an option.
