OK. At the risk of being silly, one more point :
* Since we can create unpublishing requests signed by the private key,
we _can_ delegate the ability to unpublish. We just give somebody
else a copy of these signed requests. The problem is that now we need
to communicate the signed unpublish request to someone else, and this
could be noticed.
The y=SHA1(x) allows the ability to unpublish to be delegated to someone
without needing to contact them directly. As long as the y values are
publically known we're OK.
