Wine securityflaw: Protect against root

Excuse me, but I don't think that any of these proposed methods will
live up to any real malicious code. Personally, I believe we should make
A. Not require root
B. As secure on it's own as possible (i.e. - not open to any problems
not introduced by the hosted program).
These two should allow securing Wine to the point where it is up to the
packagers and to the people calling Wine to do their tasks, giving them
the tools to do so. I don't believe we should, or even that we CAN,
solve security problems introduced by insecure deployment.
The only thing is that we should make secure deployment as easy as
possible, not that we should make insecure deployment impossible. The
later is both unobtainable, and will hurt usability.
