49 I've found several alternatives to cmd in the Cheese Shop - CmdLoop, cly, CMdO, and pycopia. cly looks wonderful, but I haven't been able to get it working under Windows, and that's a show-stopper for many potential sqlpython users. In any case, none of the alternatives are based on cmd - they're written from scratch, which means that a cmd-based app would need complete rewriting to use them. I like sticking close to the Standard Library whenever possible. cmd2 lets you do that.
