Re: [ITPOLITIK] Folkebiblioteker og DRM

Jeg mener selv, at have fundet et område, hvor det rent faktisk er berettiget at anvende DRM. Men det er jo ikke lige en hyldevare i open source-miljøet. Det tætteste jeg er kommet er vandmærkning af MP3-filer, men det giver kun en sporingsmulighed og ikke en kopisikring.

Hvis vi nu lige et øjeblik tilsidesætter den filosofiske og moralske diskussion om DRM er en god ide, og beskæftiger os med det tekniske...


Er det så overhovedet *muligt* at lave DRM med open source software?

Hvis vi antog at der fandtes en open-source (GPL) afspiller der overholdt DRM, ville det så ikke i ethvert filfælde være muligt at hente source koden, fjerne DRM-begrænsingerne og så lave sin egen ikke-DRM version af afspilleren?

Hvis man vil distribuere en "open-source baseret" (GPL) afspiller, kræver GPL så ikke at man medsender nok source til at kunne "cracke" den?

Man kan have DRM supporten i afspilleren, i operativ systemet eller i hardware (som i TiVo sagen), men indebærer DRM ikke automatisk minimum ét closed-source / proprietært software (eller hardware) led af rent tekniske grunde?

Er open-source DRM overhovedet en mulighed?
