Apparently Sony has implemented a 'rootkit' in the latest PS3 firmware v3.56.
"Essentially Sony can now remotely execute code on the PS3 as soon as you connect. This can do whatever Sony wants it to do such as verifying system files or searching for homebrew. Sony can change the code and add new detection methods without any firmware updates and as the code executes remotely there is no reliable way to forge the replies."

So I suppose this can also be implemented to verify which files are/were streamed?
