My gut feeling, based on the messages you attached from your ISP admin is that they are not going to let you run Zope. They don't seem to be very flexible. Flexibility costs money (in terms of support)... and, as stated in a previous thread, hosting Zope is a lot more expensive than basic web hosting because of the resouce usage. The resident size of Zope looks to be dependent upon the size of your database, cache parameters, etc. It's probably minimally 4M though.
