    As I said before, the beginnings of this extension is already in the code.

    As an underlying principal, I think it is reasonable for an admin to
    have control over what a client can store on the server.

    I suppose that if the annotations stored by the client are only used by
    the client (config options, etc), then I don't have any objection to
    using just the mailboxes ACL.

    If however, we're talking about tagging a mailbox so that the server
    treats the mailbox differently (calendar data, etc), then I think we
    want to tighten up the access.

    I'd like to hear other opinions on this topic.
