It doesn't come easy's Journal: Sony stealth disables DRM restrictions?

In what has to be one of the most ironic twists so far in the Sony DRM debacle, a blogger named Nicholas Colyer discovered that by adding the $sys$ to the front of his CD burning software he can now copy as many CD's as he wants. No mention of any real details about the programs involved (apologies to all you hackers out there). One has to wonder, though, just how many other software restrictions can be bypassed by this useful feature? If the stealth function of the original rootkit turns out to be good for lots of other fun things, this could be a real situation for Sony. Nothing forces you to run the stealth removing patch, and I would bet that Sony didn't include an automatic update feature (in which case they would not be able to automatically disable the stealth feature from afar). Might they have to resort to cooperating with Microsoft to add a patch to the regular Windows update process?
