Hi Jake, Thanks for your reply regarding the setting up hosting facilities. I don't think the overhead of running multiple zopes will be a problem (until I approach > 10 clients). 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? 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. However, if multiple sites share the same ip address, how would I send the request to the correct instance? (using zserver) I hope these questions make sense. Tim Haines.
