I haven't communicated clearly.  There may be a number of
different ways to power cycle depending on the attributes of
the host.  The point was to separate them into classes, then
add the right one to the machine object, granting a uniform
method that does what I mean.  There may be other methods
that come along with being one or another kind of hardware.
This seems over-abstract and indirect.
