You might want to contact CD Projekt RED, I think they'd be more than willing to remove the DRM. Then again, they may have done it because they wanted the GOG version to be the only fully DRM-free one.
Good proposal. Will contact them in the following days and will link wiki pages. For The Witcher GOG .exe, we'll have to wait. Download is almost 10 GB big, and I have some other games to test first but it will be in a day or two.
