After the call went out for a compass app APK be delivered with the Othernet it made me think what other than news and learning aids would leverage from a one way data channel.
I am thinking, Cuba, DPRK, Kashmir, Hong Kong type situations where security updates are important, an updating repo on the Skylark serves thae same purpose as a fully online Android or Linux software repository so everyone gets their daily/weekly software updates. Due to storage requirements perhaps require a USB flash drive to enable a software repository feature.

https://tails.boum.org/ (a secure USB bootable Linux OS for most computers; uses TOR)
If a larger drive is connected the below might be useful for someone with a computer or Android device but no network access.
Lastly if a licensing arrangement with https://www.overdrive.com/ and the http://www.ala.org/ or a consortium of university libraries could be made it might permit an Othernet user account to receive a selected bundle of recent e-books or audiobooks weekly with automatic expiration.
