Couldn't we also track this the other way round?
As in, have the working copy know where the meta data is located?

I guess the next question would be where to put meta data about
meta data :) I'd suggest a mandatory .svn directory at the WC root.

Please let's not just punt on this. Working copies may get renamed/moved
for any number of reasons, sometimes beyond control of individual developers.

E.g. network shares that are mounted at different paths on different
systems -- I know that is a stupid setup but in reality this kind of
stuff exists in the wild, and it would be probably a PITA for many
people if Subversion wasn't able to work in such environments.

I'd rather assume that working copies get moved around all the time
(in their entirety) than assume that they never will.

We could _always_ have a .svn directory at the WC root, right?
And if this directory does not host the meta data itself, it could
provide a pointer to where it thinks the meta data should be.
