Ok, I'm trying to integrate a multicast protocol handler and I've successfully been able to get messages to the ESB, I think.  I'm actually just using a Gateway Listener and a NotifyTopic action.  Is the NotifyTopic's topic ESB-aware?

So, now I want to provide a simple action to bus-based services to send a message out to my multicast protocol.  What am I missing, I can't seem to dig this out of the examples or the documentation?  Is just a custom action handler?

TIA,
