I asked for this on the zope mailing list a few months ago, and while 
it's true there is a unique ID for each zope object, it seems to change 
each time you move the object (and probably in other situations) . I'd 
recommend to generate your own ID as a property of the object (you could 
monkeypatch some base class) and use this instead of the uid provided by 
zope. This is imho something that should be included in the zope core, 
but a well made monkeypatch can solve the problem in the short term.
