keep in mind that they can draft all the laws they want, they still need to get them past a court and possibly a jury.
hence this will be something that doesn't cut the $RevenueSource (user) off, otherwise they can't be caught again, and again.
no it will be akin to a fixed penalty notice, where its basically up to you to prove innocence (its hardly going to be worded so they have to prove guilt since thats a non starter, otherwise they would currently be pushing that through the civil courts without the beyond reasonable doubt clause)
no it will be a fine, maybe £30 per 'offence', but maybe £300 if you challenge it, so people will just pay up. enforcement will be privatised, and will end up with the ISPs themselves getting half the fine as 'payment' the rest going to some gov agency, in theory to hand out to the media companies, but in practice kept by the treasury.
worst of all worlds really. media companies get *nothing* and the users get shafted on flimsy 'evidence' thats not possible to disprove since *you* won't be able to get access to the required logs from them.
the only other way is a mandatory license, and thats a huge can of worms as well, especially since then you can download, and upload anything, can't see the yanks liking that much.
either way it has to be something that can't be circumvented by simply using some encryption, hence has to be akin to the tv tax. you pay a 'tax' on your internet connection (probably with a seriously complex scheme behind it to justify $crapita getting the contract to run it) that gives you some sort of vague rights, but not too many.
he gov then sit on the cash, give some to "good causes" and keep the rest for admin costs, and tell the media companies to go swivel.
once the media types brought the dragon of legislation in they must have realised they would never get the lions share.
the law will also be very badly worded, won't catch the serious file sharers, but will result in a lot of fines being sent to laser printers and people without internet connections.
personally waiting to see if a valid defence will be "my connection was too slow to have commited the alleged download in the times indicated"
doubt the ISPs will want *any* part in this unless they get to enforce it and keep the cash, or a large part of it for admin & investigation, why would they?
