Many questions can actually be answered by the spec, e.g. this what
section 22.214.171.124 in the 0.9.1 version says:
Most integration architectures do not need this level of
sophistication. Like the amateur photographer, a
majority of AMQP users need a "point and shoot" mode. AMQP provides
this through the use of two
- a default exchange for message producers;
- a default binding for message queues that selects messages based on
a match between routing key and
message queue name.
In effect, the default binding lets a producer send messages directly
to a message queue, given suitable
authority – it emulates the simplest “send to destination” addressing
scheme people have come to expect of
The default binding does not prevent the message queue from being used
in more sophisticated ways. It
does, however, let one use AMQP without needing to understand how
exchanges and bindings work.

Not really. But what is you specific concern about this?
To be honest, I can't see any requirement that you have that would not
be best served by a dedicated chat server - for example a proper XMPP
implementation. It seems to me that AMQP/Rabbit *may* not be the best
choice of software for your actual requirements. Why don't you look at
something like ejabberd, enumerate the requirements that you have that
can't be fulfilled it and then consider augmenting it with Rabbit to
mop up the unsatisfied requirements?
BTW please do keep messages on list - it is unfair to the community to
go into private mode and it also means that nobody else can answer
your question - making the Rabbit team unable to load balance the
handling of questions.
