Do you want to send a single request to ONE server from the pool, or do 
you want to send the request to EVERY server in the pool?

If you want just one server to deal with the request, then it sounds 
like a load balancing problem. Look at the code for omniMapper (in 
omni/src/appl/omniMapper) for an example of how to redirect a request 
to another server. You can use this mechanism (LOCATE_FORWARD) to 
distribute requests amongst a pool of servers.

If you want every server in the pool to respond, then you probably need 
a broadcast mechanism of some kind: you could use the Event Service 
(omniEvents).
