LPMud was used as the basis for the first Internet talker, Cat Chat, which opened in 1990. TMI Mudlib The TMI Mudlib from The Mud Institute was an attempt to create a framework driven mudlib for the MudOS LPMud driver. It consisted of many contributors to MudOS as well as people who became influential in the LPMud community. When TMI began work in 1992, a mudlib was generally packaged with both an LPMud driver and a complete world built on top of the mudlib. As a framework-driven mudlib, the goal of the TMI mudlib was to provide only examples for world objects and place the burden of building a working world on the game developers using TMI. TMI implemented the first InterMUD communications network, when MudOS added network socket support in 1992. TMI never realized its vision and shut down. It was quickly followed, however, by TMI-2. Unlike TMI, TMI-2 was somewhat independent of the driver team. It leveraged elements of the original TMI mudlib and eventually released a somewhat workable product. Though it never achieved the success of its sibling the Nightmare Mudlib (also based on the original TMI mudlib), it did influence many developers, and the lessons learned with TMI-2 led to the successes of the Lima Mudlib. In 1992, MIRE, a multi-user information system producing customised newspapers was built based on a modified TMI driver. In 1993, the TMI-2 mudlib was used to create PangaeaMud, an academic research project designed as an interactive geologic database tool. Though Lima took lessons from TMI-2, Lima is a completely independent codebase. TMI-2 is still available, and often used as a learning tool, but not typically used today for new LPMud development. Notable MUDs based on TMI-derived mudlibs include The Two Towers set in Tolkien’s universe and Threshold. Server software MudOS is a major family of LPMud server software, implementing its own variant of the LPC (programming language). It first came into being on February 18, 1992. It pioneered important technical innovations in MUDs, including the network socket support that made InterMUD communications possible and LPC-to-C compilation. Its name reflects its focus on separation of concerns between game driver and mudlib. Genocide was an important development testbed for MudOS from 1992 to 1994, but switched back to the main LPMud branch, citing speed concerns. FluffOS FluffOS is originally forked by Wodan from Discworld MUD, released as a roll-up patch to support
