We just announced VaultPress to the world. You can get your invite here. I’m very excited about this service because it is the first step toward my dream of every WordPress, regardless of where it’s hosted, to have best-in-the-world network (cloud? ) services that take all the worry and hassle away. People invest so much time, money, effort, blood, sweat, and tears into their WordPress-powered sites — they deserve for that to be 100% secure.
