I have a JavaScript Windows 8 App that stores its data in a JSON file in Local Storage. I would like to sync this JSON file to the SkyDrive to enable users to use the app on different machines. Is this possible and has anyone seen a good resource for implementing this?
Another note, I am building a Win8 Phone companion app, so I would like the data accessible to the phone as well.
I thought about using Roaming Storage, but there is a data limit, and didn’t want to limit the app that way.

It appears that WL.backgroundDownload and WL.backgroundUpload are what you want
