Interesting about Réunion having African IP addresses - it is constitutionally part of France, and there shouldn't be any issue with people there or other French overseas departments having access to French video content.
The UK regards its overseas territories as separate countries, and even in Gibraltar you officially can't watch Sky, though you'd never know it if you watched TV on the Rock. Although people get the full Sky package for only £60 a year, nobody in the UK cares as Gibraltar's only got 30 000 people and the local station (GBC) gave up trying to compete years ago. If it were bigger, local broadcasters could buy the rights and kick up a fuss.
