Hi Peter, Diversity is a good thing. :-) I don't have any problem disagreeing with you, offering my own opinionated (and probably somewhat ham-handed) views .... and also congratulating you on your success and wishing you <b>sincere</b> good fortune with your upcoming book! Honest! Moreover, If you'll provide a brief, ...detailed... , concrete example of how this thing would work - I'll try to consider it openly and come up with an intelligent comment. It may be that I, (and perhaps others), don't understand what you are asking. <Ill-considered Guess> Is it a shipping manager that buys a 'shipment tracking object' from company A, a 'customer payment object' from company B, and a 'graphics object' from company C --- and they all "play nice" together and her folks can give her charts on percent of quarterly shipments where payments have been received to date?</I-G> .... Or is it something very different? Ron L.
