Build permanent summer and winter venues. Use them for training and sanctioned events every year. Split the take between the countries, based on the number of athletes they send. Sit back and laugh while you watch them argue over the crooked accounting.
Crooked accounting is what the Olympics are all about!
How much is paid for the broadcasting and media rights?
How much for Juan Antonio Samaranch & family?
Does the IOC pay for anything?
I was going to post the same idea regarding permanent venues. Put the winter games in Svalbard, Norway and the Summer games in Greece. Same place every time.
