Lightscribe

Hi All
 
Does anyone know what happened to lightscribe, the system was quite common but seems to have just disappeared.
 
For those wondering what I'm on about, lightscribe was (is?) a system built into some optical drives enabling the label to be etched on to the coating of a lightscribe disc.
 
It seemed to me to be an elegant and simple way to label discs without mucking about with adhesive labels etc.
