I’ve been analyzing the current state of "secure" messaging, and my recent tests with Signal have highlighted some persistent vulnerabilities inherent to any stack relying on standard TCP/IP. Even with strong encryption, metadata leakage at the ISP/CDN level and the reliance on kernel-level interfaces like TUN/TAP remain significant privacy bottlenecks.

I’m curious to discuss the feasibility of a user-space only stack built in Rust that completely decouples identity, addressing, and transport to mitigate these leaks. My current architectural hypothesis involves an identity layer using hardware-backed Zero-Knowledge Proofs—via TEE or zkVM—to handle authentication without persistent identifiers or central registries. For addressing and routing, I'm thinking of a minimal RINA overlay where Distributed IPC Facilities (DIF) allow us to route between processes rather than nodes, effectively moving away from traditional IP-based addressing. This would all be wrapped in a "blind" transport, such as Ockam or shadowsocks-rust, to make the traffic indistinguishable from generic noise to any external observer.

I’m still weighing the practical hurdles, especially how to best bridge RINA's recursive logic with a user-space transport like Ockam without requiring root privileges. I'm open to suggestions on alternative technologies or implementations that might achieve this same level of isolation. If anyone has thoughts on the practical hurdles or existing foundations that could be leveraged here, I’d really value your perspective. Definitely feels like there's a lot to dig into.
