If I understand this correctly, the pickles would then be compatible
between 2.6 and 2.5, unless you did from __future__ import
renamed_modules, which would make the pickles compatible between 2.6
and 3.0. This sounds like the best solution to me, especially if the
old names are still available after the future import, as all that
would then be needed it to repickle all the pickles to convert from
2.5 to 3.0 pickles, right?

So, if I understood this correctly, that sounds like a perfect solution. :)
