Netflix doesn't really have different streams for different devices; they have an evolution of encodings and some devices are still using the older ones. They started out with WM3 then segued into VC-1 with WMA sound, then to AVC with DD2.0 sound (5.1 DD+ surround and closed/soft captions available on limited set of titles). The new stuff is specifically set up for adaptive streaming (smooth transition between lower bit rate, lower PQ encodings and higher bit rate, higher PQ ones as available bandwidth on your connection fluctuates); it also separates out sound and captions so that they can offer different versions for the same title.
I don't think that anything uses the WM3 set anymore and they probably no longer update it. Most devices still use VC-1 and very small but growing set of devices implement support for 1080p, 5.1 sound and captions.
But to answer you question I don't think that VUDU multiple sets of encodings, since they controlled firmware on their original players and nothing much has changed, feature-wise, since embedded devices showed up.
