I appreciated the President's thoughtfulness on this issue, but this post doesn't add anything beyond a "Me, too!" to what Obama said.

He links to this article:

Which ends:

"I would love to hear from folks who really understand security if such a scheme would work or not (and/or point me to people who have thought about this)."

So again, very little added to the conversation. This really is one of those cases where a lot of technical expertise is required to usefully comment, and I appreciate Obama conceding as much at SXSW. But there seems to be many others just throwing out magical solutions without understanding whether or not they would actually work in practice.
