OK, so I've found out the answer.  Here it is for anyone who's
interested.

The answer is: etags.  I can now press M-. over a call to any function
or class call and jump to its definition anywhere in Zope.  Yay!

Here's a recipie for anyone who's interested.

The etags which came with my distro didn't have support for python, so I
donwnloaded the latest version:

  ftp://fly.cnuce.cnr.it/pub/etags.c.gz

But this is broken too, since it doesn't index indented functions.  It
was pretty simple to fix (patch applied).

Then I just did something along the lines of

$ find . -name '*.py' | xargs etags

Having done all that, I then found out there's a tool in the Tools
directory of my python distribution which does it for me >:(

http://makeashorterlink.com/?T11225F7

Anyway, highly recommended.
