Ok. Let me put it in this way :-)

What I’m looking for is the possibility to implement an application 
level version control inside Zope.
I guess revision could be handle in the same way as OID are handled and 
guide the gateways what revision to get?

Would this be possible with the scenario you describe?

Also would it be possible to use a ZODB storage from the gateways? In 
other words stack a version-aware storage on top of another storage that 
implements the revision repository.

Johan


PS. I keep this discussion on zope at zope.org, but next question I will
send to zodb-dev at zope.org.
