Bitfrost and the One Laptop Per Child project
I saw this security system mentioned on Bruce Schneier's blog and as he says it looks interesting. Security by not putting in the dangerous bits. Security that's aimed at being easy to use. Security turned on by default. Distributed secure keys for updates. We could do with more systems like this. I'd not taken much notice of the OLPC project to start with but they're coming up with some really good ideas. I see these laptops selling well in the first world too.
