In the case of a file being taken over, yes, this would be the most
efficient way of bring the text-base into sync. Of course, detranslation
(newlines & keywords) would need to be taken into account, and it would be
a rather large block of functionality to import into the SVN codebase. It
would need to be added to both svnserve (through libsvn_repos) and
mod_dav_svn in order to become a new function of the libsvn_ra interface...

Sussman, do you think this would be the way to go rather than simply
checking checksums? It would be a much longer road to follow, but the end
result feels cleaner to me :-)
