Can I update content remotely on multiple players at the same time using the BSN.cloud?

Yes. BSN.cloud allows you to organize your players into groups, and schedule content to be deployed to one or more groups at the same time (or on different dates at different times). 

Simple File Networking allows you to configure multiple players to check the same folder on your remote web server for content updates. To update your players using this method publish changes locally in BrightAuthor:connected, then transfer those changes to your web server.
