[Zope] PCGI + ZServer with the same Zope installation

Hi there! I couldn't find this documented anywhere, so I decided I would just see if I could get an answer from the voice of experience - is it possible to run Zope both from PCGI and ZServer at the same time? I am building a site where I want some stuff to be over SSL, so I have to use PCGI for that stuff, but I want to use ZServer to serve out the rest of the (non-secure) part of the site. Is this possible? Are pcgi_publisher.py and ZServer 'aware' of each other somehow? Setting up things this way wouldn't result in two Zopes getting started, would it? Anyone know about this? --Brian
