I wish there was a router that could automagically handle encryption. This way even grandma could plug in her "freedom box" behind her router and have secure communications. Maybe a simple web based admin page to manage configuration.
Would love to see this, i.e. some open source box, that just handles OpenVPN and TrueCrypt for the local network. As an idea it sounds not that overtly complex to realize - just hoping somebody will take something like this one day on Kickstarter.
