Well, the possibility of DOS if you set the counter too high, and the
possibility of replay attacks if you fail to save the last state when
you shut down comes to mind :)
(Not saying it's not possible to create a workable solution, just that
it's not trivial and requires careful thought to not break the security
assumptions of the protocol).
