Is there a way for a single request to be received by all pool members

Hi Kevin, you mean the will the GGSN needs to receive a response from the anti-spam servers?

I was hoping you knew the answer to that question. Your original post indicates a potential need to send the same request to multiple pool members. This isn't generally possible (in a simultaneous way) if you expect to get a response. You could certainly send the same data out to multiple logging servers, or even potentially to multiple hosts (serially) using a sideband process, but ultimately it depends on what you need to happen and the timing of events. Can you elaborate on the intended traffic flow?
