AMQP helps you distribute messages to clients that are network connected and
can do some jobs when receiving messages.
So you can distribute data to your clients using the json protocol to send
messages containing data to the clients. And from the computing client you
can send back the results always using the json protocol. This only if you
don't want to use a central database... but this depends on how you design
your app.
