i guess the reason amazon doesn't have many distribution centers is because they are expensive

she outsourced the problem by having amazon marketplace

now every kindle is distribution center (cheap)

looking at this trend, she might be better off creating a kindle for movies

her strength is not in rental (why safari bookshelf is unchallenged ?)

if she really want to be in movie rental, maybe safari dvd-rack model (download high-res per dvd chapter or streaming lower res for full, 3 titles/rack/mo) is a long shot

the success of youtube indicates that not everyone cares about dvd-quality clips, they simply want to watch it now
