Dot Mac Does Terabyte Transfer

Apple’s dot.mac service suddenly has upped the data transfer ante from 10 gig a month to a terabyte a month. Niall Kennedy sent me this this link to this screen shot, from another dot.mac user, but I have not been able to see similar upgrades on my dot.mac account. I would guess it is a progressive rollout. The increase in bandwidth for transfer perhaps has been inspired by people wanting to back-up their videos (purchased at iTunes store) or perhaps this is the beginning of something new: like an online PVR?
