Ownership management aside, I'd say one of the key features of Thorsten's pointer containers is that their interface automatically dereference the pointers held so as to create the illusion that it is the actual elements that are being stored in the container. This feature is not supported by Boost.MultiIndex, and I don't think both libs can be used together to implement this artifact. ----------------- It will depend a bit on 1. how you define iterators for your indexes, and (basically, you would need to forward these from the container) 2. if the user can decide what container to use underneith. but I think its going to be difficult. br Thorsten
