Intermud-3 (I3) is a router-mediated protocol for communication among MUDs. It originated in the mid-1990s LP/MudOS community, but deployed implementations now include other drivers and non-LPC gateways such as this project.
The historical proposal is valuable for packet vocabulary, service intent, and network architecture. It is not a complete modern conformance suite:
- some sections describe proposed behavior rather than universal deployed practice;
- old mailing-list and FTP locations are archival and may no longer exist;
- implementations accumulated compatibility conventions not captured by one normative document;
- router operator policy and endpoints can change independently of the protocol text.
The proposal credits Greg Stein (Deathblade), John Viega (Rust), Tim Hollebeek (Beek), and other early implementors and contributors. This repository does not attempt to rewrite that history; it separates historical specification from current gateway evidence.
- Use the original I3v3 proposal for historical protocol intent.
- Use the MudMode specification for the router-facing frame transport.
- Use current operator references such as Way of the Force and MUD Standards for deployed endpoints and community context.
- Use this repository's service matrix, packet models, tests, and validation record for claims about the gateway.
