Re: PGP ?
Actually orthogonal to the legislation (as I read the article).
It'll mean you can't sell gnupg in Oz. And if you sell a tool that implements PGP, you'll have to be prepared to cooperate with the stasi.
Basically what it seeks to prevent is not unbreakable encryption, but rather making unbreakable encryption available to the Great Unwashed.
Those of us who can use gnupg are the tech equivalent of people capable of manufacturing drugs or weapons. You don't wipe us out, but you come down heavily on a person who supplies them to anyone else.
Ironic that it was an Aussie (Eric Young) who originally wrote the software that later became OpenSSL, back in the days when that would've been illegal in the US.
