Re: thoughts on future regulation of encryption
1i - That's not a counter-argument, that's just saying we'd be *really* screwed!
1ii - How about proving the technology works before making it a cornerstone of the anti-terror strategy?
2i & ii - Terrorists with jobs in finance and healthcare continue using strong encryption (you're not going to force Barclays to get a new license every time they move a server, are you?), corrupt license issuer staff sell dodgy licenses, or sneak extra IP addresses onto genuine licenses.
There's probably possible countermeasures for those ideas too, but the added complexity will make it even more cumbersome, and introduce bugs.
3 - steganography to hide the strong encryption. Say, embed your strongly encrypted material in a live stream of your home security camera (extra irony points for pointing the camera at your back door), and wrap that in the government-approved backdoored encryption. Even if the security services figure out what is going on and capture an endpoint, they won't have the keys to decrypt the strong encryption for other endpoints.
