webapp manifest, local storage, etc... about events-app

caching the schedule offline will be easy enough, since we can just use appcache to make the browser cache that particular webpage for offline access.

as for each individual session, this could prove harder, however we could get node to generate the appcache manifest file, and add the url of each session to it

For now, I think we should only bother caching starred sessions. No point caching too much… just the things people think is more important.
