Another interesting RIAA calculation: this one is from a letter to the inquirer:

"When might this actually start affecting us? When 1 out of every 10 is affected? That would mean they'd have to sue six million people. That would take,...(6,000,000/75 = 80,000)... 80,000 days.. or 219 years! They'd have to sue our great grand children!" [inquirer]

I might suggest that everyone will feel "affected" when 1 out of 100 people are sued. It will still take them more than 20 years just to serve all the subpoenas.
