Proxy Mode
In proxy mode SurgeNews acts as a router connecting the user almost directly to the upstream or back end server once they specify which news group they want to read, in this way you can have a single point of connection for incoming users, but actually have the news stored on any number of back end news servers.
Typically you would use this to spread the storage & processor load over multiple cheap servers, typically one for mp3's one for 'dvd's one for 'other binaries' and one for 'non binaries'. As the servers are not taking a full feed you can use cheap IDE drives and medium speed processors.
The widearea quota limits in SurgeNews let you apply user quota limits over these multiple servers.
