That depends on the use case.

Is the number of consumers constant?

Can you arrange for all consumers to subscribe before messages are being 

Are all your consumers operating at approximately the same rate?

Is the total rate of consumption greater than the rate of publication? 
(It better be, or you will run out of memory eventually)

Depending on the answers to the above, the normal round-robin 
distribution mechanisms employed by queues may suffice.

PS: please keep the list cc'ed.
