http://memorycloudapp.com - We built this 100% in MacRuby 0.10 and it was a blast to build. Started building it in 0.6 and worked on it all the way to Lion and 0.10. Never had 1 issue in app approval with it being macruby! About MemoryCloud -- MemoryCloud stores your favorite photos and videos for you, allowing you to reclaim precious hard drive space. Not backup, not synchronization. MemoryCloud is simple and safe storage for the files that typically take up a lot of room. Here’s how it works: photos and videos occupy a lot of space on your Mac. With MemoryCloud, you just drag and drop these files to store them on the cloud; drag and drop again to retrieve. Smaller versions of the originals are kept on your hard drive so you can still view a favorite photo any time you want. Want to know what is being stored for you? MemoryCloud places a small watermark on your compressed files, so you instantly know what has been archived to the cloud. MemoryCloud provides a simple alternative to multiple CDs, memory cards and external storage devices, allowing you to carry smaller versions of your media with you. Finally, you don’t have to choose between cherished memories and hard drive space. MemoryCloud offers: * Safe storage utilizing Amazon’s state-of-the-art cloud technology. * A simple way to organize and access your favorite photos and videos. * Full compatibility with both iPhoto and iTunes. * The only cloud storage solution that also allows you to reclaim precious hard drive space.
