I heard about this on the chromeoslounge.com forums. It's a personal cloud app that runs on multiple platforms including Tonido's own plug server. I set it up on my arch linux server with a little help from the forums there, and so far I've been very impressed. It looks like this will replace the previous solutions I had in place for music, files, and photos on the cloud. I've opened it up for my family to use, but we'll see if any of them choose to participate.
I hope to finalize and maintain a pkgbuild in the arch's AUR for tonido in the near future.
