this still permits publishers to make a verbatim copy, make their own 
cover, publish it and not mention tex live at all;

(1) Is tex live as a bundle copyrighted? (with all freedoms of using / 
copying / adapting you mention), if so, you may request that it's mentioned 
(2) In order to be able to help users, if the image is used, a cd cover 
should mention (1) the name tex live, (2) the version number, (3) the 
editor, (4) url OR on te covert point to a readme where the user can find 
this info (he/she should be aware of it) OR have a proper pop up mentioning 

even if we cannot demand it, i would make the suggestion much more stronger 
(keep the 'requests', omit the 'not legal req.'); if some publisher has 
doubts, he will definitely contact the team -)

So, get me right, I have no problems with copies of tex live in a book, but 
it should be recognized as such (just as a linux cdrom mentions that it is 
some brand of linux and runs on some kind of platform, what kernel is 
used); same for tex live. Actually, one may wonder when one may use the 
name TeX Live, i.e. after what changed / additions the name is no longer 

Maybe TeX Live should be a trademark.
