Offline / BackgroundSync for back end dashboard?

Hi guys

Great to see some basic offline functionality (like comments) using the BackgroundSync API. I would like to experiment with adding offline / background sync functionality to the backend dashboard. The use case is a client who uses the backend to record notes and add manual Woocommerce orders during face to face appointments with customers. Currently if the internet connection goes down, things need to be hand written and entered later.

It would be great if they could continue working offline, adding posts and Woocommerce orders or order notes, then have it all automatically synced via BackgroundSync when the connection comes back up.

Is there a way of enabling this already? If not, could someone suggest what code I would need to add or hack to start experimenting? Is it just a case of extending the functionality of the existing admin service worker somehow? And if so, is there a way of specifying which particular sections or URLs to enable it on?

Thanks!
