Well, I'm just not that lucky! Or is that unlucky? It is possible,
though, that someone, somewhere will be. If the story reported
earlier in this thread is right, someone already has been.
Wouldn't a way around some of the (unlikely) problems be for gpg to
give each key on the keyring a guaranteed unique number (guaranteed,
for example, to be unique on that keyring), and allow users and
front-ends to specify a key by that number? This might even be as
simple as a number generated by pre-pending the number of the key in
the standard --list-keys output to the fingerprint.
