bnetd is a software package that was reverse engineered from Blizzard Entertainment's Battle.net online multiplayer gaming service, providing near-complete emulation. The first version was released on April 28, 1998 by Mark Baysinger, who at the time was a student at UC San Diego, under the name StarHack because it was originally meant for StarCraft to connect and chat together. On April 29, 1998, Baysinger received a cease-and-desist letter from the Software Publishers Association who threatened to file a lawsuit unless three demands were met within three days. In response to the email, Baysinger requested for the SPA to wait until May 7, 1998 to allow Baysinger time for legal advice which was granted. On May 7, 1998, Baysinger directly addressed to the three demands but received no further communication from the SPA.
Due to time limitations, Baysinger abandoned the project in December 1998. However because the project was open sourced under the GNU General Public License, the project was continued by a group of volunteers and as Blizzard released more games, the project was renamed to bnetd.more
