A big use case that we want to support for our apps is to be able to push
out security policy for domains that we know are being targeted.

We can't push out security policy for every site on the Web into clients but
we can easily cover the top 95% of targeted sites with a pretty short list
of policy statements.

And a huge sub case here would be to pull up security policy for an
employer's site for a company machine. This is done today with real utility
but its all proprietary.

But that really should be agile across multiple protocols. So for example,
HTTP, IMAP, POP3
