Quebec: very unlikely, it's more the politicians than the people, and that would be too costly because Quebec would have to assume its debt, could not have the canadian dollar as currency and would not enjoy a special status.
There are only two provinces that give more money than they receive in Canada: Ontario and Alberta, Quebec would lose a lot of resources if it separated.
Flanders: nah, they bitch a lot but I don't think there ever was serious talk about separation, except maybe at the beginning (when Belgium and the Netherlands gained indepence from Spain).
Taiwan: it's independent, only that not formally, not likely to declare it because China opposes it and the western countries don't want to upset China now.
Chechnya: not in a million years, the Russians will not allow it.
Palestine: likely there will be some sort of Palestinian state at some point in the future, not while Arafat is in charge though.
Scotland: no, they are ok like they are, there some bitching but that's all.
Catalonia: where is that?
Basque Country: no, the ETA has lost strenght.
Kosovo: possible, but it would probably join Albania.
Alaska: are you serious?
