I think Apple's main objection would be click-clack noise of B/S switches. If noise-reducing techniques were employed which managed to preserve the crisp, springy tactile "breakover" of IBM B/S switches but minus most of the key and spring noise, leaving only a pleasant faint "tic" at breakover, then I think Apple (and their customers) would be more receptive. This is meant as a significant upgrade, both in terms of price and performance, but I think those who value a great keyboard would be interested enough to buy them. If made in China, in moderately high volumes and by a high-quality vendor such as Foxconn, these could probably sell retail for around $250-300. I also have in mind a highly-serviceable construction method using individual switch modules and none of those blasted plastic rivets to pop off.
