Well pc users can use remote controllers too, but still it will be never equally balanced.
And I think that pcusers would have the biggest advantage, since pc users can use 1337 mouses that have macro buttons etc and gamer keyboards with special stuff to improve your skill, while PS users would always have the same remote.
Still this is a unexplored area, if some company brings up a good solution for this, I'd have no problem with it. But for now it would be just messy and unfair.
