I should also mention versioning of keys at this point. People who care 
about the 'strong' key usecases almost certainly care about being able 
to recreate old artifacts. Whatever key scheme you decide upon, you 
should expect that it will need to be changed/iproved over time. So 
please ensure that you have easy versioning included in your cache 
calculation/checking functions. YBD's scheme is already up to V9
