There are many successful projects out there being based on the idea of ungueasable URIs. TAHOE file system for example is a completely distributed FS with no management. Your client is the only one that knows the URIs. If your device is compromised of course is a completely different matter. Microsoft can also listen to your Skype calls as they have access to both the client and the server.
Basically, we implemented enough anonymity and privacy in SylkServer for those who care for almost zero cost. Beyond this, any management scheme requires some serious development.
