The ASF file format is patented (US 6,041,345), and the official specification
prevents you from distributing an open-source implementation. There is a
reverse-engineered specification, but thanks to the patent it's illegal. But
since this code doesn't allow any transcoding and in fact promotes ASF, I can't
see why would MS want to stop it.
