*sigh*. You really miss the point.

RT is merely the tracking system. Nothing more. The tracking system
should not hand out, to third parties, information relating to an issue
which could be used via other mechanisms _outside the tracking system_ to
control the issue.
As I said in my previous mail, code to do this will be written, and my
employer at least will be using it. ( Actually, I'd additionally argue
that we're required to do this as per 4.6 of RFC2050/BCP12 )
As for knowing the account number != authorisation, try the example below.
Farfetched? Its happened a number of times that I'm aware of. In all
cases, 'authorisation' was done simply by knowing the ticket number, and
convincing the issuer (Big Transit) that you were related to the problem.

Big Transit: Hello small ISP, you are ticket #123456789, whats the
Small ISP: We have a DoS going on, and it seems to be originating
from evildudes.com. They've even been bragging about it
at http://www.evildudes.com/attack/small-isp .
Big Transit: ok, we'll take a look
( follows link via tracking system, evildudes now have
knowledge of #123456789 and surmise that it's related
to Small ISP. EvilDudes, being Evil(tm), decide to get
Big Transit to disconnect Small ISP merely by using
knowledge of the ticket number. )
Big Transit: Hello there, whats your ticket number and name
EvilDudes: We've got case #123456789. My boss has delegated this
to me, and I'm Joe Bloggs.
Big Transit: Sure thing, I'll just update the ticket. Ok, whats
the current problem; that DoS still ongoing?
EvilDudes: Unfortunately so, and we've found that our router is
developing a fault from the traffic. We've got the router
guys looking at it, but until they fix it, we're going to
use our backup link. Do you mind just blackholing our
link with you so the EvilDudes will give up?
Big Transit: Oh my, sounds bad. We can do that. Say, I've
noticed that our records indicate that your got Acme brand
routers. Do you want me to get our Acme contact to
EvilDudes: They'll be onsite in about an hour, so we don't need
you to do that. Thanks for your assistance.
Big Transit: My pleasure. Give us a call when you've fixed the
problem, and we'll re-enable the link.
