	Tim raises some interesting points, I'd like to focus in on
one small section, that of controlling what software runs on a
machine.

	I have no issue with a user choosing the software that runs,
but lets consider the Microsoft CAPI model.  In it, there is control
over what runs, but it exists at the vendor level.  This is moving
away from the personal computer, and back to the timeshare model,
where control over what you run is partially in the hands of the
vendor.  Giving up this control of your computer is a step in a
dangerous direction.

	However, creating 'execution kernels' with cryptographic
authentication and resource controls is something that would be very
useful in a number of places.  Tim's selling of CPU cycles, stamps and
the like dovetails with something I wrote last December
(www.homeport.org/~adam/java.html) on the need for granular controls
in Java execution.

	So, I'm in agreement that we need resource allocation
controls, and I want to stress the need for those controls to be
configured by the owner of the computer, not the author of an
operating system, or by government policies.

	When they buy me a computer, they can decide what runs on it.
