How does this help using more than one version of ZODB (the original
example)?  The version you get depends on which account you're logged in
with?  That could work -- for some definition of "work" <wink>.  A problem
is that, at least on Windows, ZODB gets installed directly under the Python
installation's site-packages now, and the native site-packages trumps
(appears earlier in sys.path than) anything .pth files add.  We would have
to install ZODB elsewhere all the time (not necessarily a bad idea!).
