[rabbitmq-discuss] Pub/Sub Guaranteed Delivery

Hi all. I'm new here and to RabbitMQ.

I'm hoping if someone can advise me with an idea i'm having to guarantee 
messages delivery to all subscribers in a pub/sub scenario.

The out of the box pub/sub technique in Rabbit doesn't delivery messages to 
down/offline subscribers. This way, I have been thinking of having a sort 
of subscribers manager that would create queues for each one -- no fanout. 
I guess the attached diagram describes better what I'm thinking. I know 
there's the price of a higher coupling, but I think it's still simple.

Another point: I don't want to use other frameworks by now (NServiceBus, 
Twisted, MassTransit, etc) as my current scenario is really heterogeneous. 

Any advice, suggestion, or real cases will be really appreciated.

Thanks in advance.
