Belated thanks on this help with ExternalObjects, Michel.  I got this 
working with our ZPublisher/PCGI objects into zope, but I'm stuck on one 
issue:  we encode the HTTP session in the URL, and have a dictionary class 
that is invoked to get the session object from a __getitem__() call.  It 
works file with ZPublisher but isn't working with ExternalObjects in Zope.

A sample URL is:

         localhost/Zope/sess/Z8Q/home

...where sess is an external object declared in zope containing a 
dictionary with an entry for Z8Q.  I am using the old BoboDictionary, 
subclassed to override __getitem__() with code to look up the Z8Q key and 
return a session object.
I also set __getattr__ = __getitem__ ...

Michel, Amos, anyone -- ideas for what's going wrong, or what else I need 
to do?  (Error output below.)

TIA,
Michael
