<i>I think you’re misreading the publishers, Patrick-- I haven’t seen any of them proposing "windowing", except as a retaliatory move against Amazon</i><p>You're incorrect.  From the horse's mouth:<p><i>This past Thursday I [John Sargent, from Macmilla]n met with Amazon in Seattle. I gave them our proposal for new terms of sale for e books under the agency model which will become effective in early March. In addition, I told them they could stay with their old terms of sale [i.e. the ones where Amazon acts as a wholesaler and can set prices], but that this would involve extensive and deep windowing of titles.</i>
