The main goal is create flexible library for syncing browser's local data with server and make the process of creating offline-applications easier.

• WebWorkers to sync data with server in background and does not lock main UI
• The polyfill which works with IndexedDB, WebSQL, localStorage for storing data effectively in modern browsers. Best idea is launchair or store.js
• Ability to sync data using chunks similar to Evernote EDAM
• Remove strict relation from Backbone.Collection during the sync process.
