To be honest I support this bill, anyone stupid enough to get cough downloading stuff should be banned from the internet, and possibly reproducing.
(sarcasm)
EDIT: Seriously though, assuming this does get passed, it will be very easy to doge, if not when it comes out then a while afterwards hackers, in my experience at lest, are nothing if not tenacious.
It will achieve very little, it will infringe on the privacy of the public, and, worse of all, if governments get powers like this, they rarely tend to give them away. France passes a bill like this, it could be the first step on a long road...
Besides, if why are they even doing this? As I understand it it's because many of their musicians are getting pirated so much they can't make ends meant, you want to know what I think? Well, you're reading this post, so I'll assume you do.
The only reason they're getting raped by piracy is because they suck balls! If they were better more people would buy their songs and they'd make more money.
Because of this, millions of crappy 'artists' will be allowed to continue to stagnate the music business, France, you should be ashamed of you're selves.
Plus this kinda thing makes piracy seem cool, in fact, I might go pirate a move right now.
