Hello,

Is this as simple as setting up multple instance homes and having them all point at the one version of zope, or do I need one install of zope for each instance home too?

You can run a server full of Zopes from a singular Software home. When you want to upgrade the Zope instances, you just change the start scripts in the INSTANCE_HOMEs.

I guess the other thing I need to think about is how a request is directed to each instance of zope. I know I can get an instance to listen to just one ip address, so if each domain had it's own ip address, that would be fine.

Individual IPs make things convenient.

However, if multiple sites share the same ip address, how would I send the request to the correct instance? (using zserver)

You can run multiple Zopes from the same IP, you just have to offset their ports. Cheers, Jake -- Jake Berglund <jwb@imeme.net> Online Community Building http://imeme.net - Affordable Dynamic Webhosting http://nconsequential.org - modern audio architecture
