You're asking for the upcoming std::unique_ptr, but AFAIK boost 
currently does not provide it (I like to be corrected here). There 
exists a public domain implementation provided by Howard Hinnant, which 
comes quite next to its final interface (which has yet not been decided, 
but personally I'm quite sure that further changes are only marginal),

)

If you replace some used tr1 utilities (static_assert, 
tr1::is_reference, ...) by currently existing boost analoga, it should
work for you, I guess, hmmmh, aeeh, if you have a compiler that 
understands the new rvalue references....
