I recently came across a real-world use of steganography which hides extra data in the LSB of CD audio tracks to allow (according to the vendor) the equivalent of 20-bit samples instead of 16-bit and assorted other features. According to the vendors, "HDCD has been used in the recording of more than 5,000 CD titles, which include more than 250 Billboard Top 200 recordings and more than 175 GRAMMY nominations", so it's already fairly widely deployed.
Yeah, right - and green felt-tip around the edges of your CD improves the sound, too. Cheers, Ben. -- http://www.apache-ssl.org/ben.html http://www.thebunker.net/ "There is no limit to what a man can do or how far he can go if he doesn't mind who gets the credit." - Robert Woodruff
