[Zope] External Methods ->syntax + file access = how ?

Great. Thanks to all who answered..

1. Poll Product

Very helpful, as it mentions the namespace conflict in the README confirmed by
Rik Hoekstra. Not quite working yet, but I am sure this is the main problem.

It recommends installing PIL in 'site-packages' directory. Is this an older
setup, now replaced by the 'Shared' directory? Or is there a difference
between
Win32 and Linux Zope installations?

2. 'Extensions'

OK. so if I understand correctly:

A. Python Modules go in 'Shared' with __init__.py at each sublevel there.
B. Python scripts to be used as 'External Methods' by Zope go in 'Extensions'.

Q1: If these python scripts want to "open" other files in the system (MIDI,
Text, Image, whatever) What do they need to do? 
What is legal/illegal from Zope? ie: Where can these files live?

Q2: To create a nice linked list of External Methods. What is the syntax for
'External Methods' similar to  <dtml-in objectValues(['Folder', 'Image'])>
'ExternalMethods' or'External Methods' don't work...

Is there a complete list anywhere of objectValues() and objectItems()
parameters? 

Thanks
