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!)
