In the old thread i already mentioned my fear that this is useless without the notion of community. Each portal can already have its own theme, security and pages. With the URLFactory you can already do what you are talking about. Now if you want separate groups of users (one per domain) it would not be possible at the moment. It would require refactoring that cannot be achieve in 2.6.x for backward compatibility. Feel free to complete and add your thoughts on the different threads started on the subject.
