Anonymous ticket approval; BCC as CC

Hi all.

We want to enhance RT by these tasks:

  1. Allow anonymous ticket approval. In other words, we create ticket,
    send it to the user. Ticket has some URL in the body, like:
    https://rt.company.com/approve?hash=TICKETHASH
    So, when user receive ticket, he click on the URL and ticket become
    approved. If we use common approval system, any user can see all the
    tickets, but it’s not allowed.
  2. We want to send such tickets to the group of users, but each user
    mustn’t see other recipients. If we use BCC, recipient in the MUA looks
    ugly, like ‘undisclosed-recipient’ so we want to create something like
    simple mailing list, when each user from group receive it’s own email.

Any ideas for these tasks?

Thanks.
