you might be able to achieve that with webstorage? you might not need something that fancy to achieve that specific goal.
I'm looking to better understand how to store data in the app like extensive text and such without using webstorage.
Also I know that in some past testing with my coworker, we were able to get C2 to talk to the Google App Engine to pass text data using the AJAX object.. so that might be what you would use to pass json data back and forth.
