I agree.  Fortunately OS vendor types do hang out here.

Do note that the password history loss is at the customer's choice in
the solution outlined by Greg, and that an old 1DES key will only be
encrypting old passwords.  I think that's reasonable.

If you're point is that a tool could re-key the history, then I would
agree, and that'd be nice.  I'm not sure what priority I'd give such a
tool, however.
