I hope that your reference to "used car salesman" is not in reference to
my offer to host Zope until the logistics of ibiblio hosting is
solidified. Sometimes, I have a hard time discerning your intent from your
e-mail's tone, Lawrence.

It would appear to me that there is still some need to solidify the design
of the application currently envisioned and to establish a consensus on
the platform(s). It might behoove us all to revisit the deployment
architecture.

The primary issue appears to be the serving of content off a NFS store. If
multiple Zope instances access a ZopeDB stored on NFS, then corrupting of
the database is highly likely. A dedicated raid system might be in order,
or researching the Zope architechture to ensure multiple instances of Zope
do not corrupt the ZopeDB.

I would be curious to see how the data-structire will be stored ( what
exactly? ), or perhaps Zope serves as a meta-database on top the core
mysql db? Somethings to reflect upon... maybe reverse store object
references in mysql? Speaking of mysql, which version is in production @
ibiblio?

And just to clarify, I offered my server as a working Zope prototype, not
as the official store for all permaculture.info content. Having the Zope
instance hosted anywhere at this point allows for the collection of
Apache/Zope server statistics and use patterns. Collecting this data will
serve as a hard metric for required server capacity planning in future
endevours. I anticipated at least a six month window before ibiblio could
deploy Zope effectively.

I definitely can *not* host all intended content on the scale as infered
in previous posts, especially streaming media.
