It's promising, but somewhat impractical yet: it renders twice as slow, and for 2k normal map requires about 1.2 GB of RAM. More work is needed to make this particular method useful in practice.
There are also a few other papers at Siggraph that deal with similar problems, and more specifically scratched surfaces. It's not clear yet which one would be the best to implement.
