Netflix, are they joining Amazon?

Netflix, the DVD rental company has been making ruption in its share prices (so say Businessweek). Businessweek believe that Amazon could soon make an approach. With Amazon already acquiring Shelfari, Amazon seem to be cranking the investment up to increase there search facilities (and like businessweek, Amazon's unbox has hardly been a great success). The acquisition seems a pretty good one, as with there database on sales would greatly add to more longtail sales.
