[Nero] LightScribe Direct Disc Labeling is a new technology that offers consumers and businesses a simple, no-hassle way to burn professional, silkscreen-quality labels on their CDs and DVDs. Using the same laser that burns data in their disc drives, users burn their data as always, flip the disc over, reinsert it into the drive and burn a precise, iridescent label with their desired text and graphics using the same laser that burns the data - no printer, permanent marker or adhesive labeling is required.

Hey, that’s pretty freaking neat. According to the press release, Nero will support LightScribe in the February update for Nero 6 (not yet posted). More information on LightScribe can be found on their website.

Just as an FYI, after further reading it does look like you need a "lightscribe enabled drive" to support this.
