Thank you for the reply. I'm also a fan of publish subscribe. That's
why I try to build this easy API using the protocol buffer as data
definition and data wire format. I have previously used tibco
rendevouz, but is too expensive and the code is close. I'm also fan of
OMG specifications, DDS is a great choice if you want a very

solved by pub/sub, and you may need a client/server architecture (I
still recommend CORBA). Yes I know you can make a wrapper to simulate
a request/reply by means of pub/sub, but it is not elegant (as Tibco
