I agree, don't try to duplicate the mess that people moved away from (hint, everyone sane wraps ib-verbs in another model that can actually be used and understood...) > But we know we need more "complete" solution to let people understand and accept > our idea.

We are happy to answer it. Sure, that sounds like a great goal! thanks, greg k-h
