As is mentioned in this new post from Tobias Schlitt, the eZ systems folks are working toward something called "eZ platform". They've even poublished an article about it to map out their plans.

This article presents an overview of the architecture and development process of the eZ platform, the PHP application platform by eZ systems. The eZ platform will be an Enterprise Open Source software suite based on PHP 6, consisting of a flexible group of expandable building blocks that can be used to create a wide range of powerful enterprise applications for the internet.

This document summarizes the results of meetings and discussions among the core development team at eZ systems during April and May of 2006.

They talk about the goals for the platform, the architecture of it all, their development plan behind it, and the two phases of development:

• Phase I: eZ application server
• Phase II: Functionality plugins

Of course, there will be software requirements for the resulting utility, and they are always happen to get more people involved with the project.
