You can use UVmapper to easily create a coded .uvs file to distribute (free and professional versions available at this link). Then anyone with the original .obj file and UVmapper can re-create your version of the model. You can often also distribute the .cr2 file for models when you want to share new morphs. But there are important exceptions - like Victoria 2 and Michael 2, as explained at the DAZ site.
