It's probably too hard to find out which font is proprietary.

dvips already lists all fonts on STDOUT, isn't it sufficient to put an
asterisk behind each font that had been loaded entirely and then issue
a message like "*) Some Fonts had not been subsetted" at the end if at
least one asterisk appears?

The message is just an example.  It should be understood by people who
do not know what subsetting is.  But English is not my native
language, feel free to provide better suggestions.

Hans, is this ok for you?  Or is it still too crappy?

I don't see that there is any need to change the map files.

Usually there is no need to download an entire font.  The map files
provided by TeX distributions are set up to do subsetting by default.
My only concern is that people rely on this and do not notice that
they violate against licenses because something happens in the
background they are not aware of.

Of course.

Sounds quite straightforward:  An asterisk for each font which is
included entirely, independent of the map file entry.

No, he didn't.  It was an idea which came up during the conference
dinner, but he changed his mind quite soon.  I just metioned it to
show that I'm not the only one who sees problems here.

Karl, if anyone changes some font names, I suppose you are the first
one who will notice this because he will ask you to update the
fontname database you maintain.
