[Zope] Staging CMFStaging PloneStaging et al

[Michael Havard]

I'm still having difficulty getting CMFStaging to work with our setup. When 
attempting to run the install for PloneStaging I now get an error 
"LockError" "/staging/Stages/Development not lockable".
So in digging around trying to find out how to fix that error I'm reading a 
lot of material that suggests that I'm traveling down the wrong path, 
specifically because CMFStaging/PloneStaging is not a production level and 
also because it looks like Plone is going to be going a different direction 
with staging/versioning in a later version.

So I'm kind of at square one with this problem of staging again.

DEV --> QA --> PROD

Going back to an earlier thought I had I wonder if this might be able to 
work:
Setup the Plone site within the main db (data.fs). In the Plone directory 
set up a mount point for a secondary database for content (content.fs). 
Develop the templates, security, and functionality as normal, create some 
test dummy content inside the content folder through Plone. When it's time 
to test in QA have a script copy over the DEV data.fs as data_v2.fs then 
fire up a new ZEO client for QA using that DB. At that point we should have 
the newest version of the Plone site and retain whatever content (from 
content.fs) that was already in QA. In QA it gets tested and approved and we 
perform a similar update through script to PROD where it gets tested for 
validity against the already existing production content (content.fs). At 
whatever point we verify that the new version works we point users over to 
the new ZEO client(s) and switch off the old ZEO client(s)

The trick here is that what's in content.fs is created seperately from 
general development of templates, security, and Plone functionality.

My question would be 1) can it be done this way 2) are there any 
repercussions as far as cataloging, session management, locking, etc. 3) is 
there a better way that's been tested and feels production ready.
