You might want to plan ahead a little next time. A lot of us have these devices, but the chances of you getting someone willing to give up their box at the last minute is slim to none, especially for a Monday Night Football game.
Some, like me, are also leery of giving out the information on our boxes. My box is sitting in Oklahoma City, and I live in Poland. The person letting me connect in the US knows nothing about my box, except the location. She cannot help me if anything gets messed up on my box. If it gets hijacked I can do nothing about it until I return to the US. That would suck, since my daughter and I share use of the box to watch programs from the US.
If you plan to use this type of service often, it might also be worth investing the $150 to get one of yuor own. They are easy to set up, and almost maintenance-free. Mine has sat since last December with no issues, and I have watched TV from all over the World with it. In fact, I am watching it now, and seeing the current news regarding the fires in San Diego.
