In case it helps, the WebDAV versioning spec does a reasonable 
job of explaining the approach required for "sane" container 
versioning (you can read a lot of the justifications for the 
decisions in subversion in this).

At a very high level, you really need to be able to treat 
containers as containers of "bindings" or references rather 
than as containers of real objects. Doing that in a backward 
compatible way with current Zope apps is a tough task (which 
is why we haven't tried for a fits-all solution).

I have that sinking feeling that I may have been the last to touch some 
parts of it, which according to our grand tradition may make me the 
owner :)

I'm pretty familiar with the internals, and I don't think that 
those have changed much. Let me know if you have any questions and 
I'll do everything I can to help.
