I should stress that above is pure speculation on my part. All I know with a high degree of certainty is that the firmware size is at or near hardware limits. Slim folks may yet surprise and introduce Plays-For-Sure support in a future firmware. The DRM decryption can not be done server-side because that would defeat the whole purpose of streaming protected digital files. The decryption must be done in hardware or software at client side in a way that prevents the end-user from capturing the decrypted digital stream. Napster is using Microsoft's Plays-For-Sure DRM, which by the way has been abandoned by Microsoft in favor of a new DRM scheme in Zune. The Squeezebox and its derivatives support Rhapsody's scheme in which the audio files are split into two pieces during the encoding process. Rhapsody streams a large piece (which they call Residual Audio Data, or RAD) that contains most of the audio data but is useless on its own. Then they stream a tiny encoding of the original file (called the Essential Audio, or EA). The EA is united with the larger file to render a decrypted stream on the fly.
