I agree that this is a political problem, and needs a political solution. In the meanwhile, a couple of years ago, I started working in a team to work on this: https://register.blib.us - It lets your software/server manage your friendships (social network), and lets the hardware sit anywhere in the world. At some point, we plan to go open source, so that backdoors are patched (or known openly). Uses openid for auth, and provide enough providers in different countries. Its not adhoc, just point to point encrypted between trusted parties. I would love to hear ideas on how to make this rock solid. And of course nothing better than users who care.
