Thanks for the suggestion - I've actually been working on this, along with
other memory management policies. The smart pointer policy is relatively
although not quite as easy as making the template parameter a pointer type
I use new, delete and clone in the framework. Nevertheless, I should be
able to
get that policy up and running pretty quickly. I was also trying to create
a further
policy that used a single type and stored it by value rather than by pointer
normal STL containers) - unfortunately, the policy for that is proving much
than I originally thought. I'l probably abandon my second idea and just
policies for smart_ptr and normal pointer versions of the code.

I've browsed the code, but unfortuantely, I've spent a week away on business
haven't had a time to use it in anger yet, or study the code in any detail.
My first
impression is that you have done a good job - but I'll get back later in the
with a more detailed review.
