[Zope] multiple zopes with apache

[Sean Kelley]

Hi,
I just setup apache 2 on windows on port 80
Now I want it to proxy a few zope instances.  I setup zope to run on 
8080 and all is well.  I have an apache subfolder proxying the instance 
of zope.

Question is, what is the best way to add addtional zope versions?  
Should I just run them with another port number?  I assume that the 
apache server will hand everything off as 80 so I could choose something 
like 8081 for my second zope instance with no problems right?  Is this 
how its normally done or is there another way?
