Yeah, we're "spiritually" trying to do a clean-room implementation --
not for any legal reasons.  Our hope is that one would be able to
write a z-machine by using nothing but the spec.  I suppose we can
always look at frotz, malyon.el, or any number of other
implementations.  We'd still like to see the spec clarified, though.
