Accounting proxy to multiple hosts

Hi, I have successfully been running freeradius as an accounting proxy. Next step is to be able to proxy to multiple hosts... actually it will be a proxy to the real RADIUS server and then (what I can only describe as...) replication of the accounting messages to at least 2 other servers. - I only want the response from the real RADIUS server to be sent back to the originator - the responses from the other (replication) servers can be dropped/ignored Is this possible to do? Is there some better options that you might know of?
