Instead of using API calls for user navigation, you can keep a synchronized local mirror of whatever subreddits the user is interested in. I have a repository somewhere with a thing that does that, through Reddit's .json URLs, mirroring subreddits into Git repositories full of JSON files, and then serving a minimal local web interface with real time updates. I'll make a note to clean it up and publish it...
