Many thanks for the elaborate response. In my original thread post I
suggested the exact same approach, only you formalized it much better.
Of course RabbitMQ scales well in terms of queues and messages but
does it also scale well in the number of exchanges? Can it easily deal
with hundreds of thousands of exchanges (since we'll have one exchange
per user)?
