I warned everybody the stuff was coming down the pipes.
This is their method of dealing with content protection and it is going to
pollute the hardware!  The next thing down the pipes will be a requirement
for IPC hardware encryption.

CPU(crypto)<->Memory(crypto)<->Framebuffer(crypto)
ata(clean)<->diskcontroller(crypto)<->Memory(crypto)<->CPU(crypto)
scsi(crypto)<->diskcontroller(crypto)<->Memory(crypto)<->CPU(crypto)
CPU(crypto)<->Bridge(crypto)<->Memory(crypto)

Just watch and see!
