Quite a few limitations would have to be put on the program in order to make it as "fair" as possible (and even then not everyone will manage to download it on J2O), such as setting a restriction on the maximum resolution, enabling it for singleplayer only, or, like with the publicly released Ultrawarp, have the resolution changer require an unique access code, generated by a separate program, to run. Every time the program is opened, it would generate a different 'lock' code and therefore need a different unique 'key' code, reducing it to whatever became of Ultrawarp.

Actually, I think it's no longer available for download anymore). I also don't think OL gave out many access codes this year.
