Maybe someone can help shed some light on something I've been looking around on the forum about.  The PHB and other things you own can be shared in games pretty easily and are an amazing feat in themselves and I've never had an issue with it.  The only thing I'm curious about is if the sharing function will ever be expanded?  More games, more players, or for that matter unlimited players and unlimited games that you are the creator of.  Perhaps a subscription level or another version of the books(upgrades) to allow this to be possible?
