I think the larger problem out of all of this , is that they've nailed one person, spending hundreds of thousands of dollars, to probably get £20 a month paid to them from the mom, and the millions of pirates out there are thinking 'Damn, sucks to be her, and now my chances of getting nailed for this are 1 in ten million instead of zero in ten million...*logs back onto pirate bay*'.
They've got two real options, find a way to hammer millions of people for breaking the law, and do it cheaply, or get innovative and find a way to make buying music more attractive.
For me, I'm currently out of work, but when I was working I'd be buying a few cd's and dvd's each month, based on what I'd seen on TV, or online, and yes, from stuff I'd downloaded, partly because it feels like the right thing to do, but partly because I like having big shiny collections of 'stuff' on my bookcases.
Now, there's a slight lack of big shiny collections when it comes to digital distribution, but, is there anything to stop them including a download of the CD or DVD cover with your download, or hell I don't know, some kinda loyalty scheme where you can trade em in for posters, books, keyrings, etc, stuff that can't be downloaded!
As I'm currently on limited funds I admit I'll be pirating things occasionally, but its mainly TV and older games, and if those games show up on Steam I'll buy em there, because they're cheap, and they'll work with no fiddling about. Once I'm employed again I'm sure I'll end up filling my house with crap I don't need once again however.
I think one of the main barriers the RIAA have to get past is that there's a generation at least that mainly thinks there's nothing wrong with file sharing.
