I propose a Restricted Creation Interface - when an ObjectManager constructs it's Add list in manage_main, it first checks with each addable class if it's instances can be added in this specific ObjectManager.

The place where this is needed most (IMHO) is for ZClass factories. So there needs to be a way to create meta type filters through the Web. On the other hand, the plugins framework by Phillip Eby solves this problem in a nice way. I'm hoping to eventually modify the plugins framework so it's more accessible for ZClass development. Do you have an application where plugins won't suffice? Shane
