Missing Mac Software

Over at Macsimum Perspective, Dennis Sellers asks What Software is still Missing on the Mac?

Your mileage may vary, but my number one Mac OS/X software desire is packet writing software for CD-RW and DVD-RW so that rewritable optical discs can be treated as [really] big floppy disks. I was hoping that it would someday become part of Toast Titanium. But with Roxio selling its consumer software division to concentrate on Napster, I’m not holding my breath.
