Pandora is cutting me off, noooo!

I just received an email from Tim Westergren, the friendly exec at Pandora. Apparently Tim thinks I stream too much of his kickin' tunes. They're setting a cap of 40 hours as a result of the great internet radio debaucle of 2007, and he says of me, "Most listeners will never hit this cap, but it seems that you might."

Ok, so I listen to internet radio a LITTLE bit.... but I am resolute, just like traditional radio, I WILL NOT pay for internet radio. I've used Live365 and Slacker in the past, but found Pandora to be my favorite. So far the options are to pay $.99 after you reach 40 for unlimited songs the rest of the month, or pay $36 (too much!) per year for unlimited.

So here's the real question, is it 40 hours per ISP address or per user account? As soon as I run out this month I'll find out!
