Chromebooks etc have offline versions of users' Drive files, so is there a way to use the Realtime API, which though apparently inaccessible offline, does work just fine offline? (my app starts in an 'inMemoryModel' mode).
Problems include that Google disallows cacheing of their API's, and that when a manifest-enhanced single-page web-app is run on a disconnected Chromebook, the user is shown a "This application cannot run offline" screen, or similar.
What if anything, is Google's plan for this, and other similar Drive API situations?
