Developing Nations Creative Commons license

So today I learnt about this new and stupid Civil Code that is soon to be approved in Spanin, but I also learnt about the Creative Commons license for Developing Nations. The CC Developing Nations license allows you to invite a wide range of royalty-free uses of your work in developing nations while retaining your full copyright in the developed world. A developing nation is any nation which is not in this World-Bank list of high-income economies. For example, you might be a musician, writer, photographer or researcher that wants to maintain full copyright in North America and Western Europe, but welcome use by others in the country of Brazil.
To mark your work with the CC Developing Nations license, just go here.

Funny PS: CC licenses are protected by a CC license as well.
Serious PS: it's still not very clear how CC licenses work outside the US, though there are several projects to adapt them to as many countries as possible, and eventually the whole world.
Naughty Fruitman PS: i still haven't taken the time to copyleft my blog with a CC license.
