hehe no, i've been looking for such thing for some time and didn't find anything. what are you working on? oreans (themida/cv) engine uses yacc/lex btw :p
i ran into a yacc generated parser several times, most recently, while looking at the firmware for canon ixus camera's.
it has an embedded scripting language.
another one: the qualcomm gsm stack uses yacc to parse at commands.

igorsk: interesting article.
