Interesting link. The Demystifying the RCD
section will provide some interesting background for those of you who are not familiar with the terminology and approach in this part of the world (although there are one or two statements there I would query).
The RCBO (combined over-current and ground-fault protection, and thus the same in principle as the individual branch GFCIs used in America) would be an ideal device in many applications. It's unfortunate that it's unlikely to be more widely used (at elast in domestic work) until the price comes down to a more reasonable level.
The AFCI has not made an appearance here yet either. There has been much discussion over its pros and cons on ECN in the last couple of years. If you do a search on "AFCI" inb the general discussion area, you'll see many threads.
Here's one manufacturer's information: http://www.zlan.com/prod01.htm
