I'm very interested long term, and very busy short term.
But I did just read your .txt and .h files, thanks.

For the next few months I mainly care about getting to new
versions of scoped_ptr and shared_ptr, and am not convinced
a policy based approach is the way to go yet for boost.

My main objection is that policy constants are a good way
for a library to compress a large number of related by
different templates into a single template, but I can't see
how to let a user expand the set of constants, so there is
a high premium on getting such a complete set of policies
that no extension is needed.  And that will take a lot of
work.  But perhaps I misunderstand policies.
