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.
