There is obviously a market for fans to watch their games from abroad no matter who you support.
I'm surprised it's taken so long for this kind of thing to be born, because it's something that probably could have been done years ago. Games have always been filmed for goals, and commentaries have been going for decades and decades.
I don't know why the BBC have not combined their local commentaries with those who provide the video coverage, unless the BBC do film the games, and sell it to the likes of I-follow. The BBC could even offer a full commentary and video in sync as a service themselves.
