Yes. There is a relatively new feature in the latest versions of 
shared_ptr, shared_from_this.

The way you use it in Boost 1.29.0 is to the class you want to store a 
pointer to inherit from boost::counted_base. You can use multiple 
inheritance if you already have another base class. Then you can use 
shared_from_this to turn a raw pointer to this class into a shared_ptr. 
I expect this feature is going to be in future versions of shared_ptr, 
but the name of the class you have to inherit from may change.
