just an idea.
Is it possible to cascade multiple CMS hosting Servers?
The idea is to establish one “Master” CMS Server which is able to “controll” multiple “Slave” CMS servers.
e.g.: You administrate your Displays and Users at Point A. The content and Layouts are hosted at point B or C or D.
I´m not sure if my post is as clear as it should be. But I tried!
