I'm out of the country too, so I have kept up with it. I'm not sure about the Wyoming game, because it is on Versus, but every other non-BTN game will be added for on-demand streaming on the next day. So, you will have to find another way for the Wyoming game and ABC/ESPN games if you want to see it live.
However, if you know anyone that has DirecTV, Dish, Charter or Time Warner, then you can access BTN2Go overseas. That is what I am doing. They just launched it today and it is actually pretty neat, because you can watch the BTN anytime, not just for games. But, if you did this, you would need a way to see other games (which I have already figured out for myself).
edit: They will have non-BTN games available on-demand from their television partners on BTN2Go, but I don't know if it will be next day like bigtenticket.
