I don't understand why these cloud storage companies aren't targeting more verticals/niches with their offerings. It seems like there are endless (B2B) places where ZumoDrive's offering would solve real problems that people would pay for. I know in our industry (pro photography), having cloud storage that mimics a local drive has big potential. To be able to work in Lightroom or Aperture from multiple machines and know images are safe in the cloud would be huge. That's just 1 small example ... Why the focus on consumer music and photos? Seriously, I don't get it.
