Um, not necessarily. You can create regular Folders under the FwCS if you
want to keep them seperate. You can even use BTreeFolders or other
ObjectManagers, if you like. All that's required is that they support the
ObjectManager protocol. So you can have a folder for each meta_type. Of
course, the primary storage of the object has to be the ZODB.

No. The FwCS is to allow more "traditional" Zope objects to blend in data
from other sources, and/or to have trigger support.

Yes. But you don't have to place the DataSkins directly under the FwCS,
they can be any number of nesting levels below it.

Pretty much, although I'm not sure why you want to pick by meta type, since
one of the major reasons for having a Specialist is for the rest of the
application not to know about specific meta types.
