I was actually thinking about this the other day - It'd be awesome to have an app designed specifically for that use case. So it'd stream a version that's as high res as your connection can support to the server, broadcasting it live to anyone on the site/app who could tag it, share etc.
Meanwhile, it's saving the full res to the phone and also trying to backfill with that as the connection allows, you could even have it use wifi direct or bluetooth to stream to other devices in the area. That way someone could have their phone inconspicuously in their pocket, backing up and uploading the content from the people recording. It'd also keep recording with the screen locked, record the location, maybe even integrate remote wiping.
