This keyboard layout, also known as AFNOR Azerty NF Z 71-300, has since be standardized. Drivers[0] are available and keyboards[1] can be purchased.
I am using this layout for more than 1 year for programming and writing in french, and it's really good. I find it even better that the international keyboard layout or qwerty.
The fact that they have considered both the programming language approach AND the natural language typing is a real pleasure.
