The use of equivalent as currently implemented handles two cases:

A single server has multiple DNS names to access it.  Furthermore, links
use the different DNS names.  I didn't want to consider multiple DNS
names equivalent simply because they have the same IP (because of the
virtual server issue), so I decided to allow the user to tell me what
DNS names should be considered identical.

Indexing multiple servers.  Another common case is multiple servers
acting as a single logical server.  Examples that I have seen include
using one server for static requests and another server for dynamic
requests.

The reason that I require the method was that I was hoping to get a
solution that could eventually index different server types (ftp: would
be the next).  No plans on implementing that in the immediate future,
but hopefully one of these days.
