Not really something I want to do, and in my case wouldn't really help
anyway, as the icon chosen quite often depends on children values.

All I ended up doing was pickling the data structures that I created
and doing some simple caching. It works beautifully. Not that Zope
helped me at all. I couldn't import modules from the Extensions
directory, so I ended up having to put things in $ZOPE/lib/python. For
testing I had to have things in the Extensions directory; two copies
of things flying around isn't nice. When unpickling under Zope, python
couldn't find the class I was referring to, so I ended up just caching
the initargs.

While none of the above hoop jumping was hard, it was a pain. I
certainly hope extensions are supported better in 2.2, in particular:

* being able to import modules from the extensions directory
* not having naming problems when using extensions under zope

I'm about >< close to ditching a Zope talk I was preparing to give to my
local Unix users group, but I'm going to see if 2.2 has improved.

I'm losing faith people..
