iOS has never been ported to anything and is entirely closed, so that's out the window (course I could be wrong on that, but I doubt it). As for OS X, probably be possible but I don't see it likely to happen (or be perfect if it does).
Although, a Chromebook running OS X would be pretty snazzy
Once a pkg is made, people will download it, and since this is new fix/first revision, they won't get needed updates or improvements if/when released. It really is better to build it, and you'll want the ability so you can update in the future as well.
While I do agree that it's better to build it, I think the way Clover works means that once someone builds it the latest installer gets moved to Sourceforge?
