The far more interesting of the two is coming this May, it is NeroLinux V3. It is not the full everything and the kitchen sink encode and decode suite, just the two main burning apps, and probably will cost the same $20 as the current one. It catches the Linux version up with the Windows one with the same burn engine.

As you can see, it also has the new interface, and supports all the same interesting bits as Windows. It can burn BD and HD disks with the attendant DRM infection along with full unicode and 64-bit support. When asked about supported distros, they said most, you should not have a problem unless you are running something truly odd.
The other one that was new to me is full disk encryption called SecurDisc. It is co developed with LG and needs a drive that supports it to read and write the disc. Right now, there is one drive that does this, the LG GSA-H55N/L. OK, I lied, it isn't out yet, but it will be in the EU by the end of April at a slight premium over other 20x burners.

The burning tech is integrated into Nero 7, and you can recognize it by the SecurDisc logo on the left. For now, LG is the only one making burners with the tech, but the hope is others will pick it up later. If they do, it has some interesting possibilities, if not, I see it going away.
No matter how it ends up, there are two promising techs from Nero. The Linux one is of immediate interest, the encryption is a longer term play. µ
