An idea that was proposed before was to delegate the conversion (and the patents burden) to the OpenGL drivers, something like using glCompressedTexImage2D() / glGetCompressedTexImage(). Not sure whether there are hidden issues with that approach (except, well, requiring an OpenGL driver with compressed textures support), but at a first glance it doesn't look as something particularly hard to do.
