Could you build this?
No Developing low-level asynchronous networking components using Linux io_uring completion queues in Rust requires deep systems programming and Linux kernel I/O expertise.
What it would actually take: This requires systems-level Rust programming utilizing completion-based asynchronous runtimes (such as `compio`) directly over the Linux `io_uring` kernel interface. The hard engineering challenge is managing buffer lifetimes without Tokio's readiness-based model, zero-copy packet parsing, and implementing the full RFC 6455 WebSocket framing specification over raw completion queues. It demands deep domain knowledge of Linux kernel internals, asynchronous memory safety, and high-performance network protocols.

Competitors mentioned: Other message brokers (general category mentioned)
Concerns raised: Unclear value proposition compared to traditional message queues, Complexity of managing append-only log truncation with multiple independent readers, Solving only half the problem space (writes only)
Feature requests: Sans-IO model support for SDK to enable different runtimes and blocking/sync clients
