Just including container/vector.hpp and interprocess/smart_ptr/unique_ptr.hpp
gives:

"warning C4005: 'BOOST_RV_REF' : macro redefinition
C:\devel\boost_1_47_0_NO_SCL\boost\interprocess\detail\move.hpp"

and many more of those.

second thing is lack of default deleter so simplest code like:

interprocess::unique_ptr<Foo> upr;

is invalid.

Imho easiest to adopt would be Hinant's implementation:

http://home.roadrunner.com/~hinnant/unique_ptr03.html

It uses own rvalue reference/move emulation which would just need to be replaced
with Boost.Move. I'll try doing that and see how it works with Boost.Container.
