There's a few pilot programs out there.... I think maybe Finland, one starting in the Maritimes (Canada) and talk of one starting here in BC too. There was one in Manitoba or Ont. in '70s that apparently was quite successful... so of course they abandoned it. ;)
of course,... ,sad, but who knows what the future might hold for our society, people are looking for solutions because the problems we are facing are getting way to big , so I'm looking at a better future, let's steem to start! :-)
