It would be nice if the self-destruct key is handled like the public keys
of PGP, where any number of certification sites can be set up, so that a
group of us, for instance, do not need to use Disappearing Inc.  but can
set up our own self-destruct keys site. This would presumably require that
the algorithms for this approach be open source...
