Actually for this sort of thing we will probably have to move to a
better model than linux/Unix eventually. Has anyone had a look at
bitfrost? <http://wiki.laptop.org/go/Bitfrost> It looks fascinating
from a security point of view. It is a complete redesign of security
of computer systems.

As for Microsoft: when are people going to start not accepting
products that can't do the job? A bit of pressure from consumers and
even companies may start to change the scene but if you have 95% OS
OEM bundling lockin most people never have anything to compare
Windows to.
