Both Greg Colvin and Peter Dimov (and others?) have worked on the idea off 
and on.

I think they are "on" at the moment.

On the main Boost list we are also looking hard at the Loki::SmartPtr.

It would be interesting to try to implement cyclic_ptr, weak_ptr, and the 
like as a SmartPtr OwnershipPolicy.

The thinking is that the future of smart pointers isn't to keep adding 
completely separate classes.  But rather to add more instances of policy 
classes to a Loki::SmartPtr style framework.

(For more information, see Modern C++ Design by Andrei Alexandrescu. Highly 
recommended!)
