Thumbs up chromecast users local stream embedded videos. bypass T-Mobile upsell

Hey guys quck idea..
Since chromecast actually uses internet some useres can't bypass upsell that's why for some reason nothing shows. Well I can assure you that this app called "web video cast" will work perfectly and it streams online videos however your phone will be searching the videos and it will stream locally to your chromecast so yea.... Enjoy it!!!!!! Thumbs up? Or na?
