Current use and fit

Retained in TinTin++, MUSHclient, and other compatible clients, but based on old peer-network assumptions.

Implementation essentials

Isolate the peer socket from the MUD connection.
Authenticate peers and handle file transfer defensively.

Compatibility and safety notes

NAT and contemporary network security complicate the original model.
Inbound messages and files are untrusted.
