I believe you could use the BOSH API:

I see that there are now docs for the BOSH api, however is the BOSH api suited to concurrent access by multiple processes? We are writing a component that will need to frequently validate that a particular machine is a DEA.

What about with BOSH?

I think the only reliable way is to listen on NATS and look for the DEA advertisement messages. Am I correct or is there a method I am missing (I'd rather call and API rather than subscribe to NATS)?
