This makes me smile a lot. Whenever I pick up a new programming language, one of the first projects I tackle is writing a port of a similar MU* server because of the same breadth of concerns, so it's very nice seeing someone else recognize the complexity and take it on as a worthy challenge. (Though, this goes the extra mile and modernizes things; I've seldom accomplished that.) I hadn't looked at doing this in Rust yet, so it'll definitely be interesting to give the code a read, particularly with the focus toward modernization.
