Yeah, well, wouldn't it be nice if only we had a system that would allow
us to grant (possibly limited) access to specific applications by, say,
issuing them a little authentication something that they could present
to the authorities... we might even call it a "ticket"... but of course,
not everything with access should be able to issue tickets, so we may
have a ticket-granting ticket and a normal access ticket...
