Hi Jonathan, some quick observations:

* Some of your includes still refer to <boost/io/...> instead of
<boost/iostreams/...> (most notably, the examples). Am I missing
something?

* In boost/iostreams/detail/buffer.hpp, you can take advantage
of boost/detail/allocator_utilities.hpp to do your allocator rebinding
for both compliant and defective compilers. So, instead of

#ifndef BOOST_NO_MEMBER_TEMPLATE
    typedef typename Alloc::template rebind<Ch>::other    allocator_type;
#else
    typedef mpl::if_<
                is_same<typename Alloc::value_type, Ch>,
                Alloc,
                std::allocator<Ch>
            >::type                                       allocator_type;
#endif

you can write:

#include <boost/detail/allocator_utilities.hpp>

...

  typedef typename
    boost::detail::allocator::rebind_to<Alloc,Ch>::type allocator_type;

(BTW, it is not BOOST_NO_MEMBER_TEMPLATE but
BOOST_NO_MEMBER_TEMPLATES.)

* Seems to me that with some moderate effort the library could
be made to work more or less with MSVC++ 6.0. If you want me
to try to help a little wrt to this, please tell me so and I'll send you more
questions/stuff via private email.
