It is only an assumption, but I am guessing that apps such as the Xfinity TV app by Comcast are setup that way so that people can not use devices such as the FireTV and the Ouya as a replacement for renting a set top box from them. Yes, I can get around this issue by going on wifi, but why use an worst connection method when there may be another way around it? Also Androids open environment is supposed to encourage the creation of alternative ways of doing things.
Looking through other threads, there appears to be a desire for an app that spoofs wifi for people who are also only on 4G or other wireless methods. Having an app on android that could spoof a wifi connection when you are 3G or 4G wireless would be just as useful for some people.
