You don't 'access frameworks' in that example. You access shared content.
Remote means shared. Some content can be shared app to app, device to device, and some is done via the OS on one device, to various apps on the other, w/the OS in the background.
Good to know I need an app on every device to deliver this access / content on any "remote" device, and there is no programmatic way to create ad-hoc connection to get this info from a remote device.
