The distributor will do exactly what you are after. Basically the distributor will control n number of nodes which use a round robin style work allocation. The nodes register with the distributor by passing a "I'm ready for work" message to it. The distributor then puts these messages in a queue. When the distributor receives the real message, it will pop the first "I'm ready" message off the queue and forward the message onto the appropriate node. When the node then finishes processing the message, he'll send a new "I'm ready" message to the distributor which will end up on the bottom of the queue.

So basically, it'll do exactly what you want.
