Anyone interested in a bit of perl I knocked up that looks for renames?

It takes as arguments two trees - and does a can for files that have
been obviously renamed - but also looks for files that have been
renamed, _and_ changed. There are two 'metrics' you can define in terms
of percentage of change.

On two kernel trees (without an {arch}) it takes about 20 seconds for a
full scan (without any cached directory info!).

Not quite sure what to do with it, but I'm also working on a tool that
will import a set of directories as project versions.

        address@hidden
                http://mjr.org/arch/{public}

Look at scan4renames.
