Personally I dubbed this "email multi-domain" support.
In contrast to the "ASP ready multi-domain" support where
you can have seperate managers for seperate domains.

One design criteria I have in mind actually is 
that we should try to be a independent as possible from the
actual tree structure. This would give us advantages in places
where users already have requirements for a directory service
and already made decisions.

It is good to ship a canocial tree design that will work well with Kolab,
but we should also prepared to deal with completely different tree
structures. Inherently I think it is possible to not demand a certain tree
structure at all.

I am thinking along two steps for the road map:
a) email multi-domain support with joined tree and administration
b) ASP ready customer-domains

a) is a lot easier to do and I would aim for Kolab Server 2.2 with minimal
changes to the clients.
