Last year we released a reactor framework that uses a smart-pointer based on  
Andrei Alexandrescu's ideas. The reactor and the smart-pointer are released 
under the same license as ACE.

>From the docs:

"The smart pointer, which is quite core to the reactor itself, is a relatively 
orthogonal set of classes that allow you to declare at compile-time smart 
pointers having specific sets of characteristics."

There's a lock policy (object/method/none), an ownership policy (owned/not), 
and deep copy policies (ctor/clone()).

I would submit this for inclusion into Boost but I'm a bit too busy to change 
the code to meet the requirements. But if anyone finds any of this 
interesting, we'd like to see the code get used.

The smart pointer doesn't inherently require ACE, but the type of mutex we use 
is based on an ACE mutex. The reactor requires ACE, but only as an interface 
(if I recall correctly), which allows it to be used in the existing ACE 
framework. I think the reactor could be easily stripped of the ACE 
requirement.
