Word yesterday was that they've dropped the 40gb a month allowance for the top tier to 30gb like the others. Thing is, like now, it's not 30gb a month, but 1gb per day.
That has implications, especially how you describe your use, as you couldn't say, I'll download this 10gb file today, as I've still got 20gb left to last me the rest of the month. The limit is per day, so anything over 1gb in one day would be over the limit...officially, but they're not enforcing it as such yet. But once they do it could cause problems for people like you whos' download sizes can be sporadic.
Really, a 30gb per month limit would be better, and more flexible, but I guess that doesn't allow them to balance the load on the system so well.
