I have developed a nonintrusive Reference Counting Handle class that supports crosscasts. The limitaions are that both source and target parameter types must have virtual methods, and that currently it don't supports access from multiple threads, Do the esteemed members of this list think that such a class would be a useful addition to the library??

It would be helpful if you explained how it differs from shared_ptr, which also supports cross-casting. See http://www.boost.org/libs/smart_ptr/shared_ptr.htm#dynamic_pointer_cast Jonathan
