I was thinking about making a similar app years ago that would use an SSH server instead. The only issue compared to iCloud (and why I wouldn't be using this just yet) is that you loose support for iCloud Photo Library. If you make a full-featured suite of equivalent apps for Mac that can replicate the iCloud experience I would pay good money for that.
