DRM *implemented in software* is fundamentally flawed. I just hope nobody
starts really using the TPM and things like HDMI that move decryption into
the display/sound hardware :(

The decryption keys are stored somewhere on every HDMI device. Way harder than to sniff out the key from a software player, but definitely doable. Don't know enough about TPM to know how secure it is, though.
