I ran into this yesterday. I recorded a "Home Video" of a school play that my daughter was in and youtube blocked it due to the music that was used in the performance. I am not trying to sell it, but sharing amongst family and friends. It would be nice if we could send a share link for single files to non plex users, so that they could perhaps watch via a web based stream. This would add a cool sharing feature, but would also promote plex amongst users that already may not know about it.
If you like this idea lets promote it. This is a feature request section ;-)
