This SiteAccess has an enhanced VirtualHostMonster.

The VirtualHostMonster has a simple form for defining the Domain-Folder Mappings for your Zope. It maps domains that you service to object managers (i.e. folders) in your Zope, allowing you to run one domain from one subfolder, and another domain from another subfolder of your Zope, without writing code.

It works whether Zope is behind apache or naked.

This improved VHM is availiable by default on iMeme accounts
