Note that, IMO, some of the best use cases for multi databases are separating catalog and session data from regular content.

Could you say more about what the benefit of this separation is,
and why cross-storage references are necessary for it?

Seperate storages have seperate object caches, that means you can "keep room" in one cache for certain types of objects by making sure all those certain types of objects are stored in one storage.
(See Paul's comments about catalog objects...)

Cross-storage references can be made to work and *should* work even though they're not strictly necessary (although they become ever more necessary if you don't use Zope's path-based traversal, which I'm not great fan of) for the benefits of mounted storages.

cheers,

Chris
