[Zope] - external methods and pickling

[Jim Fulton]

Note that external method "module" files are not really
modules.  In fact, I need to remove the word "module" from
the UI and documentation.  Because they are nor real modules, 
they cannot be used to define picklable classes.  Perhaps
this is where the problem you are running into is coming
from.

Note that you can define classes in regular Python modules
and import these modules into ExternalMethods.  Perhaps that would
be an approach that you could use.

You can try sending some details to support@digicool.com, however, I'd be
the one responding and I'm going to be unavailable for the next week or two.
