The associated constraint is that MOO (and Cold?) is single rooted. 
The whole Oz and Kansas caper becomes much easier if your give (as I
recall they did), Kansas and Oz seperate roots, with each Oz
generation devolving a new root.

Quite.  Remove Cold's requirement for a single root and it becomes
almost trivial at the base level to implement.  Then the ugly stuff is
in the automatic kick-overs to Oz, the Oz<->Kansas
inter-relationships, and the Oz generations.

Very.
