The article doesn't mention which developing country the trial will be in, but South Africa would make an interesting candidate. It has a public healthcare system that's in shocking condition, and a world-class private healthcare system, funded by health insurance, that's becoming more unaffordable (despite being funded and mandated by employers) each year because of high medical inflation. There are clear parallels to the US healthcare system, and the commodities downturn has stymied the government efforts to introduce universal healthcare, so there would be an ideological willingness to experiment.
