Sorry, I may have pressed the key combination for send :-)
This is the full message.

You can open a queue in browsing mode.

See 
http://qpid.apache.org/books/0.18/Programming-In-Apache-Qpid/html/section-addresses.html#id2512294 
for an example

In this way, when a node reads from a queue, the message stays in the 
queue. Other nodes can then read the same message.
Since you mentioned that nodes may be offline, you have to handle 
duplicates. Moreover, I don't know about the message rates and size, but 
you have to take into account the memory used by the queue on the broker.
