I see what they are getting at, I was recently traveling with an android phone, iPad, and macbook. I generally like to keep my photos organized in aperture but between android, drop box, iPhoto trying to import my pictures, galleries I had exported from aperture to Facebook, and being unfamiliar with how to manage photos on my phone there wound up being versions all over the place. I lost track of the canonical versions, and have sets with some reduncies. So if o want to get them all, I think I'm going to import all the photo sets into aperture and sort it out<p>An app that could help with this would be great. What's even more annoying is the confusion that comes with managed libraries I'm the Apple apps. Unless you're paying a lot of attention, those files are pretty much taken out of the file system already (the photos that is).<p>What Younity is attempting here sounds very interstating, but what a challenge! How can you do effective backups if you don't know where all of your files? Is the idea to have some kind of super cloud sucker thing that backs up all of your chaotic files and structure/state?<p>Good luck with this, I think you might have a great product
