How would you organize a global Rock, Paper, Scissors tournament?

A friend and I were bantering about how we should organize a RPS tournament, where the LOSER advanced and was ultimately kicked in the bum by the "winner" of the final round, and also given $10 as a pity for being the "greatest loser".

This quickly morphed into daydreams of a global event, culminating in the grand finals at the Mandalay Bay, with coverage by ESPN 12, sponsorship deals, trading cards ("Joe is known for his southpaw stance and shooting from his off-hand which greatly throws off his opponent." and per-year statistics of Win % by rock, paper, and scissors); the whole nine yards.

But it got us thinking... in today's age, would it be difficult to organize a simple RPS tournament GLOBALLY? What technologies would you use? Could you approach it 100% digitally? How would you verify the loser for advancement?

Let's even say someone was willing to put up $20k or even $100k to actually fly winners from each continent or major population region and put them up at the Mandalay Bay (btw - that hotel just came to mind because it was the first to come to mind in Las Vegas) for a 1-day event. Would that change anything?

RPS because the absurdity of it and the zero cost to entry.

We await your thoughts...
