Folder,  a believe the uniqueness of the UID is to the folder scope.  

I remember once seeing something about the ability to generate UUIDs
[was that Cyrus or something else?] but I don't know how to turn that
on/off.

Ugh, I'd advise against it.  Why not do them on the 'protocol' level?
That certainly makes the archives easier to use.
