VUDU subscribers recently got possibility to control their STB, browse move catalog, rent or purchase desire movie directly from iPhone or iPod Touch. It seems that support of Apple smartphone became a standard de-facto. Many producers of home automation systems such Crestron, Lutron, Control4 and etc provide iPhone App to control their systems. The VUDU iPhone App is good addition to that list.
BTW I like the VUDU approach to use pear-to pear technology to transfer rented or purchased movie to the customers. It makes the process of downloading faster and loading of VUDU servers less.
