I believe that the licensing terms are listed in the comments at the top of main.c in the Crafty source code. As I read those terms, if you want to do anything more than make changes for your own personal use, you need Dr. Hyatt's permission. Using a modified Crafty on a chess server appears to be one of those areas that needs Dr. Hyatt's permission, so that the modified version is properly identified as a modified version of Crafty.
