http://tex.stackexchange.com/questions/126903/print-font-name-using-luatex 
and a remark in the luaotfload documentation I understand that
font.each is not safe. This here seems to work

for i,v in pairs(fonts.hashes.identifiers)

But it does show only the opentype fonts. I don't know which table
you can safely query to find out something about normal tfm-fonts.
