[rabbitmq-discuss] Understanding Basic Get and Consume

(Using a Windows installations only)
I have two brokers set up in a federation.
Using the RabbitMQ .NET library, I am able to publish and consume messages
from and to either end respectively. This works.
Dropping out of .NET, I am attempting to consume a message via command line
(rabbitmqadmin script). The call I'm using is *get*.
>From what I understand (looking into the docs), this is a synchronous call
- so it's a call from the client to the broker. What happens when the
command gets to the broker is *broker A* asks *broker B* for any messages
(using the *upstream*). Messages (if any) then get passed to *broker A*
from *broker B*. This all happens asynchronously. My question is: Is there
an asynchronous call I can make from the command line to get a message over
a federation like the one described above? I have heard about consume but
have not seen any examples and according to the rabbitmqadmin script, it
does not recognise it.
My second question is: Given that *get *is synchronous and *consume *is
asynchronous, what is going on under the hood? Where is the difference? Are
they both calls to the broker but consume waits for a response?
