The Fork
I think that putting up a forked project for the "community" edition of Mandriva (Mageia) is good. This should become what Fedora is for Redhat, a community-driven distribution, high on Mandriva standards and willfull to embrace new technologies in Cooker.
The Company
The company should leverage Mageia by producing a derived distribution from the stable version, including former One live editions, and selling powerpacks. From the solid base, they should expand and integrate the Enterprise Editions
The Community
Having both Mageia and Mandriva, the community should try to integrate both distribution to work with binary packages in the contrib, plf and mib repositories, so you should have binary compatibility in the stable Mageia version and in Mandriva. Projects like Codeina should go on and simply just work.
The Future
We will see if the sinergy will work correctly as I hope. In the meantime, having a backup project like Mageia, will easy the transition for many users, including myself. For now, I'm postponing the migration to CentOS as it seemed so obvious to do it just a few days ago.
