So, for figuring out who won the Oregon-UCLA game last night, the system would pay out on the results of the Google search “Oregon UCLA basketball score” as of a certain time.
You need to have someone that you trust to perform that Google search and read it and then decide who won the money. Otherwise the two people who bet might disagree on what the Google search says.
A quick search shows that there are lots of websites providing a ticker of sports results in XML form. Rather than doing a google search which, as you say, would need interpretation, I think it would be more reliable to pick in advance a basket of such XML feeds, where you know in advance the precise format they’ll use to announce the result.
