This is quite true, however, I think the opportunity to quickly add code
such as music players without having to include all the ZP coding overhead
(some music players touch practically everything in ZP) would be a big win.


As an aside, I could some value in a set of methods to save and retrieve
the entire ZP state to a specific location.  This could allow some sharing
of the ZP memory such that task-a, task-b, and irq-c could all utilize the
same ZP variables, but do so independently of each other without bonking
the others' state.
