Not in this situation, they're both running on a machine to which I
have administrator and root (if you want to call it that) access.
Thus in reality I have access to *everything* that's going on in the
machine.  Whatever 'security' X wants to put in my way I can (if I'm a
reasonably capable programmer) circumvent.

me.

Not round here, no need to lock houses, it makes life *much* simpler
to live.  Security is a huge waste of human resources with very few
advantages or uses.
