Sure, no problem. Just use 2 ports.

No problem, as long as you really do have two different python
binaries on your system. Look at the "start" script in the base Zope
directory.  It'll say something like

exec /usr/bin/python \
     $INST_HOME/z2.py \
etc.
 
Change the exec to point to the version of python you want to run with
this Zope. That's all.

I've used Python 2.1 with Zope 2.3.3 on my development box, and it
seems to be OK - though I've had some odd refresh issues.
I probably wouldn't do it on a production server.

You get some warnings at startup about the deprecated "regex" module,
but that's no problem. They are safe to ignore.

Officially, Zope 2.4.x is the first series of Zope to support (and
REQUIRE) Python 2.x. If you want python 2.x, use that.

I came along long after 1.10, but I've done a couple of minor Zope
version updates and I often have two versions of Zope running to test
things out during that process.
