Hmmm.... let's see....for a start, anything on the Akamai network shouldn't be a problem....
I'd be surprised if even they allow 40 Mbps per connection. There aren't too many applications that require it. And bandwidth providers are notoriously stingy; they don't give bandwidth away. Someone who needs 40 Mbps per connection will have to pay dearly for it, even though it may cost almost nothing to the provider.
