That looks > very odd. Usually a ZEO client talks directly to a ZEO server.
I try to reduce the load of the line between the backup Computing Center and the Mainsite by having a zeo server as Proxy between the zope server at the backup site an the ZEO at the main site. Secound part is that the zeo at the backupsite can easily reconfigured in a normal ZEO when the mainsite is offline. So I don't have to reconfigure all zeoclients at the backupsite. The Data.fs is copied every hour to the backup site so that a have an up to one our backup of the data.fs in case of a desaster at the main site. A configuration like that is described in the Zope Book on page 230. Besides I have found that with a growing number of zeo clients the Zeo server gets slower but neither the CPU nor the Harddisk IO is at the limit. We have a load of 0.2 to 0.3 and disk IO arrond 2-3 MB/sec. We have 12 zeoclients at the moment and 12 more are planed for the backup site.
