Yes, however his point is that by having each Zope instance 'predominantly' 
serving one portion of the site, its cache will contain more objects 
relevant, and thus be just that little bit faster.

Personally, I find this such a simple idea that it MUST be good. (o8
So much so, in fact, that I've decided to have a crack at writing just such a 
redirector.  I feel the Zope world (and others, most likely) could benefit 
from a 'preferential' redirector.

Watch this space. (o8
