I took a list of all countries and eliminated those that are listed here. The resulting countries might have access to the YouTube coverage then (probably not, but gotta try to find some way to watch the things I can't watch live, which will be most, and won't be shown on Dutch NOS, which is basically everything except for the night sessions):
Looking at the VPN regions Norton offers, personally I've got some hope to be viewing 'from' Singapore, Romania or Ireland, which all aren't in the broadcast list.
