Currently when we compare two versions of a project in the repo view, we fetch 
both trees and then check for any differences. The problem is that the fetching 
of these trees is a none standard CVS operation which requires one command per 
folder and issues multiple commands per connection. This is a concern since 
certain project configurations (i.e. lots of folders) can cause the operation 
to take a very long time and certain server configurations prevent multiple 
commands per connection.

An alternative approach that would solve the above problems would be to 
use "cvs diff" to generate the original diff tree. The comparison of source 
would then only require the fetch of one of the two files involved. The compare 
framework already has the capability of extracting the files from a diff file 
and for combining a diff with a file to obtain the second file so it should be 
just a matter of tieing these together.
