Aye to that! I was thinking more in terms of commercial stuff where parts of the file, ie textures, could be zipped within the main zip file and bought seperately so all you as a vender would have to do is send them a key by email to unlock the zip when they paid for it. The question of non distributable portions of a CR2 would probably have to involve one of Maz' products and I'd rather not do that until I know he has resolved the issue of infringement. until then, Is there a list of dos and don'ts you would post or have posted regarding cr2s? -TJ
