My first reaction was to yawn -- that patent seems to be useful on
insecure systems, since on a secure system you don't have to worry
about running untrusted and trusted applications simultaneously.
Besides, the point of a patent is to prevent people from doing certain
things, and I have no particular interest in doing digital rights
management.
But then I thought of the relationship between this patent and the
SSCA, and it didn't seem funny any more.
