[Zope-dev] Versions: should they die?

Sorry if is OT.

I'd like ZODB and Zope to support Revisions. That is, historical copies that do not get 
removed when ZODB is packed.

Does the Version mechanism contribute to this kind of functionality? I'd like to be 
able to "tag" revisions of wiki pages and other documents, and then be able to diff 
them later without having to create a special kind of product for each object type that 
I'd like to use revisions for.

Maybe this is kind of the reverse way of doing what versions are for. We have used 
versions a little to work on a "live site". 


What would be interesting is using revisions (with tags), then telling Zope to serve 
only objects with this revision or "older", or the current object if no revisions are on 
file for that object. And .. the serving up of a particular tag would be set on a Zserver 
instance.

So, I could continue to use ZMI as normal, but run "another zserver" on a different 
port (the one that feeds the world) with a particular revision. Or I could do this with 
ZEO.

Probably there's too much overhead in this idea.
