ECP-0009: MoQ implementation selection

Status: Draft

Problem

We need a practical MoQ implementation to begin integration with iroh while the protocol evolves.

Survey (Rust implementations)

• moq-dev/moq: MoQ reference repository with Rust crates including moq-lite, moq-relay, and hang catalogs.
  • https://github.com/moq-dev/moq
• cloudflare/moq-rs: Rust implementation of the IETF MoQ Transport draft.
  • https://github.com/cloudflare/moq-rs

Decision

Start with moq-lite (from moq-dev/moq) and reuse the adapters proven by iroh-live:

• web-transport-iroh for WebTransport-style bindings over iroh.
• iroh-moq for creating MoQ sessions over iroh connections.

Track cloudflare/moq-rs in parallel for standards-aligned MoQ Transport and schedule interoperability tests once we have live relays.

Alternatives considered

• Building a fresh MoQ stack: rejected due to duplication and slow iteration.
• Waiting for browser-native MoQ: rejected because it delays core network validation.
• Starting directly on cloudflare/moq-rs: deferred until we need draft-accurate transport.

Rollout / teardown

• Vendor or depend on moq-rs crates.
• Implement a minimal publish/subscribe pipeline over iroh.
• Re-evaluate once MoQ standardization and browser support stabilize.
