Karl, you can do this kind of thing already by simply modifying the
templates.  For example, you might tweak templates/include/dir_header.ezt to
contain text something like this:

   <p>You can checkout a copy of the directory you are current viewing by
      doing the following:</p>

   <blockquote><pre>
   svn co http://svn.collab.net/repos/[rootname][if-any where]/[where][end]
   </pre></blockquote>

In the "my repository URLs don't map very easily to their disk location"
case, I admit that the EZT language won't be quite as graceful as having
some kind of custom configury magic in viewvc.conf.  But what you wish to do
should still be doable in any case.

For kicks, I quickly added a "Checkout URL" row to the headers on the ViewVC
instance at http://svn.collab.net/viewvc/svn.  I did so with the following
EZT stuffs:

   [define checkout_url]http://svn.collab.net/repos/[rootname][if-any
where]/[where]/[end][end]
   <tr>
     <td>Checkout URL</td>
     <td><a href="[checkout_url]">[checkout_url]</a></td>
   </tr>

Maybe you could do the same in the places you need this information?
