How is the meta data indexed?  How is it searched?

It is possible to export data from a Zope server and import it into another
one, or even use it directly without having to import it.  This allows us to
actually *mirror* the content, and not have multiple Zope front ends to a
single ZEO-driven database on the backend.  I do this at my job and it works

Why do you assume no one will run Zope?

How many mirrors do we really need?  Not "We want as many as CPAN!" but how
many do we actually need to have in order to support the load we expect this
service to undertake and to give some fail-over capabilities.

What is mirrored on all of these sites, the actual database or the service
which does the lookups?
