No.  Based on your bandwidth tests, VUDU limits the maximum speed at which it streams both in and out.  Additionally, VUDU makes use of “bandwidth hopping” that causes VUDU to reduce or stop any transfers when it detects that other devices, such as your PC or game console, require more bandwidth.  Of course, while watching a movie, VUDU requires sustained bandwidth to deliver a fantastic viewing experience.  Unlike other services that rely on large server farms to deliver content, as more VUDU Boxes are installed, the network will become even more efficient and require less of each box.
