Hi,
I'm looking for a way to implement a project using some copy-on-write feature, similar to how STL strings use reference counters to prevent needles copying of data. Is there anything in boost to help me out with this?

Check out Flyweight which was made a part of Boost in Version 1.38. As far as optimizations, Boost already have shared_ptr enhancements that are undergoing standardization where the control block is merged with the object pointed to; whether or not Flyweight takes advantage of this is a different matter. The only thing missing is the small object optimization.
