[Zope] Some questions regarding Zope hosting

[Juergen R. Plasser / Hexagon]

Hi!

We are going to host some Zope sites in the near future and therefore some 
questions came up:

1. When someone needs a whole Zope instance we don't like to give him a 
dedicated server. How usefull is it to run more than one individual Zope 
instances on one Server? Is there a better solution for more than one Zope 
instance? How helpful is ZEO in this case?

2. Which configuration is the "best": Zope + Apache, Zope's Webserver 
Medusa alone, any other configuration like Zope + Squid (as reverse proxy)? 
Which configuration fits which requirements?

3. When more than one user participates in one Zope instance, what is the 
preferable method to get (for the user) distinct Zope views for each user.

Thanx for your answers,
Juergen
