There's no technical reason you can't have more than one jail using the same 
file system root, and even IP -- you'll find that ps(1) in one jail can't see 
processes in the other (and can't signal, etc) but otherwise works as 
expected.  Of course, any given process has to be a member of at most one of 
the two.
