Okay, thanks. The only scenario I'm worried about is:

   3. Their custom server sends back protocol that is, in all meaningful
      ways, the same as what Subversion's own server would send back,
      yet gets different results on the client.

If #3 is happening, then I'm worried. If it's #1 or #2, I agree
they're... interesting... but I don't have any special expertise to
offer Oren (though the users@ list might be just as likely to have
answers, or even more likely, since people who write code using the
Subversion APIs hang out there).
