Hi Leonardo,
I don't think that is a good thing to adapt Zope/Plone to development  
environments (should be the
reverse actually), but I understand your problem because my  
colleagues use PyDev.

I have developed a patch for PyDev which allows autocompletion for  
arbitrary Zope Products folders
(e.g. parts/plone or develop-products) but still needs some work for  
the "goto definition" feature (which
is by the way implemented in a different way in the opensource  
version and in the PyDev extensions plugin).

I have informed the PyDev mailing list about the effort some time ago  
and I'm currently trying to implement
this stuff in a separate plugin to avoid clashing with the basic  
PyDev features; if you're interested in trying the
patch drop me a mail, but keep in mind that it's very experimental  
code and currently works only against PyDev CVS.

Another workaround would be to symlink each Products folder, but the  
currently released PyDev doesn't work
correctly with symbolic links (fixed in CVS).
