What's in everyone's best interests is that work is not distributed, but done at the source.  So, the creators make the RR textures, and put a link on the download page and people can choose to download or not.  So, your requirements, and his, are met.

Whew!  I gotta go lie down.  That took at least two brain cells.

Ok, so I shouldn't be so snarky, but really, does anyone think your post explains why vendors don't make RR textures?  I sure don't.
