There was a thread about this a while back that talked about design choices
and nested ZClasses.  Due to some of the current conventions in the
ZClasses implementation, nesting them really didn't seem like the way to
go.  You lose some functionality, and things get hard to change.  Putting
all the ZClases in the root of your product folder is probably a better
idea.  (I'm sure I'm not the only one who believes this).  

Just my 2 cents,
