Hi Chris,

Not Flask, "bottle.py", it's a microframework like Flask.
While Flask supports more things like Signals and Slots (which I hadn't
worked out yet).

However, I am making only use of zope.interface, zope.component that is
helping me in my work entirely a lot.

Meanwhile I have dropped for the single machine development uWSGI and
make use of gunicorn behind nginx, which serves well.

uWSGI makes only sense for scaling....

After that project, I'll plan something new (I do have in my head) and
love to organize my code much more and like to make use of bluebream.

When I install ztfy.webapp it's only 1 EGG that is being installed
globally, while zope2 has lot's of dependencies, and forces be to run it
in a virtualenv.

Back to the subject why I would use Zope2 (instead of Zope3).

In 1st of all why I want to make use of an application Server is that I
don't have to load everything several times.

Routines, I had written and registered with Zope Interfaces and grabbed
with Zope Component Architecture could be loaded globally and accessed

So, the server would host different application and would make use of
certain objects accross applications.

The security model of course is a different one. I'm looking for well
supported software, and I am sure as Plone is living, like it does now
Zope2 has a great success story and lot's of volunteers.

I still have some code to write, lot's of Javascript, Python and some
more MongoDB routines....

PS: About ZODB. I don't really love to rely only on ZODB.... I saw
relstorage where any relational database can be used instead ZODB.

Are there any plans to run Zope on MongoDB ?

best, Tamer
