quite simple as an idea: most Laptops and stuff dont have a BD Drive available (to no one's surprise) but you might have another PC or a headless server or a mini-server based NAS that has space for a drive. one thing that would be fairly neat would be an option to expose a decrypted virtual drive (be it a mounted folder on Linux/Mac or a virtual Drive in Windows) that gets populated with virtual files that correspond to the decrypted Metadata of whatever is on the bluray, and the video/audio files would only need to be decrypted live in RAM or something when a program is trying to access them.
that way you wouldnt need to fully rip the discs but just could watch whatever is in that PC/Server/NAS/whatever from any device that does read decrypted blurays.
