Thanks for the respin.

We are still not resolved on granularity. Stephen has said he's not sure 
if a useful policy can be constructed with just confidentiality and 
integrity settings. I'd be interested to know JJ and Casey's thoughts on 
lockdown policy flexibility wrt their respective LSMs.

These are also "all or nothing" choices which may prevent deployment due 
to a user needing to allow (presumably controlled or mitigated) exceptions 
to the policy.
