We may need two implementations:
(1) A very lean implementation for collections that contain a small number of objects.
(2) An implementation for large collections, maybe based on BTrees.

Ideally db4o would change the right type at runtime.

We did the first spike for high speed writing. Times look very good when a small part of the collection is touched (dirty).

I would be really helpful be able to configure collections to add/remove items and also update the collection itself via container.set(...) so users don't have to update the items and collection explicitly via container.set/delete.

I have started a thread in our forums to discuss requirements:

To all the people watching this issue:
It would be great if you would post your requirements and thoughts to forums too.

Thank you very much!
