Hi nut,

Excellent job finding and documenting this feature.  As for the 
developers' motivations, though, I don't think it's necessary to point 
at colusion with the RIAA/MPAA.

In all honesty, I'm surprised we haven't seen *more* backdoors of this 
type in various popular closed-source, network-aware apps.  I don't 
condone it, but I understand the mentality:  "Our network, our rules." 
Really, all it takes is one rogue developer, coupled with insufficient 
code review.

What does surprise me is that you report only delete functionality and 
not read/write.  If I was going to the trouble to implement naughty 
features into an app like ES5, that'd be my priority.

All this does is reinforce the value of independent code auditing 
(insert various pro-open-source comments here).

take care,

C
