The most realistic option is to use a library called Nvidia texture tools. Nvidia has an agreement with the owner of the patent (no idea who that is these days) that allow others to use this library without licensing the patent: https://code.google.com/p/nvidia-texture-tools/wiki/FAQ . Note that despite the name this library doesn't depend on Nvidia GPUs.
Probably good idea. They said the library licensing compatible with GPL. It also gives us DirectX10 and 11 capabilities. But it requires a time to implement into wine. I just didn't understand what is the condition to use this library? Place Nvidia copyright?
