Well, from http://fy.chalmers.se/~appro/linux/DVD+RW/
Q. Kernel patch? What's wrong with cdrecord/cdrtools? A. Nothing! Moreover, you actually need them (cdrtools). It's just that you can't use them to manage DVD+RW media itself. DVD+RW media has no notion of [multiple] sessions or packet writing, so cdrecord[-ProDVD] wouldn't really know what to do. But most important is that DVD+RW is a true random write access media and therefore is suitable for housing of arbitrary filesystem, e.g. ext2, vfat, ufs, etc.

From my understanding, its more like CD-MRW in that it does the write coalessing for you (which is why the packet driver wouldn't be needed), but it doesn't do bad block remapping so running arbitrary filesystems isn't the best way to go if you value your data.
