Selling your App in Play Store from unsupported country

Hi!

I would like to know if someone here managed to sell his app in Play Store even though his country is not supported by Google. What i found out that there are some companies in foreign countries, that offer publishing your apps under their account. Obviously they take some percentage from the sales. I would like to know if anyone here is doing this (or did it in the past), if its even worth it and what happens if after a few months Google starts supporting your country?

This is really bothering me because i cant understand why wouldnt Google try to add as much countries on the merchant support list. They would earn more money from the sales and more developers would make apps from these countries… Maybe its worth mentioning that iOS and windows mobile developers can sell their apps from these countries already for a few years now.

Cheers
