All the work to decouple Boost containers from Interprocess is already 
done, except for move header <boost/interprocess/detail/move.hpp>. A 
quick find/replace exercise can put all these containers in 
boost/container without any dependence on boost/interprocess (we should 
put move emulation in boost move).

Implementations of all Interprocess containers are now here:

boost/interprocess/containers/container/

in the boost::interprocess_containers namespace

Headers in boost/interprocess/containers just include previous headers 
implementation and hey have using declarations (e.g. 
boost/interprocess/containers/list.hpp):

#ifndef BOOST_INTERPROCESS_CONTAINERS_LIST_HPP
#define BOOST_INTERPROCESS_CONTAINERS_LIST_HPP

#if (defined _MSC_VER) && (_MSC_VER >= 1200)
#  pragma once
#endif

#include <boost/interprocess/detail/config_begin.hpp>
#include <boost/interprocess/containers/container/list.hpp>

namespace boost {
namespace interprocess {

using boost::interprocess_container::list;

}  //namespace interprocess {
}  //namespace boost {

#include <boost/interprocess/detail/config_end.hpp>

#endif //   #ifndef  BOOST_INTERPROCESS_CONTAINERS_LIST_HPP

All the work to maintain backwards compatibility is done, we just need 
to find/replace some includes and namespaces. I have already done the 
exercise with an slightly older version of containers for Boost.Move:

https://svn.boost.org/trac/boost/browser/sandbox/move/boost/container

My opinion is that containers should go to boost/container. All the 
dirty work is already done ;-)

Best,
