Idea: Nano Wagering Site

Is there a way to make a Nano wagering website where we can create our own wagers that people can bet on?

Example:

Lets say someone says we are on the path to hit 3° Celsius global warming by 2060.

I say, I'll bet you Ӿ40 XNO we hit 3° Celsius global warming by 2035.

They say. "You're on!"

But we need a wager site to place our bets into that will escrow it for us. The site would allow us to to place our bets and select the data source for conditional payout.

I am sure this could be used for other things such as sports betting and other stuff too. I am not sure the of the legal requirements for something like this, and I am not gambler, but I was just wondering if you think something like this is possible for Nano, or does anything like this exist yet?

This might be a good way to get more Nano flowing and used more.

I just think it would be sweet to be able to make small wagers on a variety of subjects. Maybe if there was a list of subjects to bet on, such as climate change topics (Like temperature in a city, sea ice extent, global warming, sports, politics, celebrity deaths, etc.

I feel like all we would need to establish this is an official data source for the bet and time-frames to close the bets. The datasets would be agreed upon, such as a government agency weather report, or whatever, and the website could probably take a small 1% rake on the outcome or something to stay profitable and up and running.
