Meh, my HDD is my personal property, and for someone to take it off of me without my consent/warrant will meet my 12 ga. shotty. Simple as that. Doesn't hurt to go ahead and secure the ol network anyway.
I wouldn't worry about it, because the RIAA has really lost popular support when they started going after kids and grandma's like a pack of half mutated rabid pig-dogs.
As for them accessing my computer without my consent via electronic means...that's hacking. Isn't that a felony???? that would be a great counter suit.
