In an interesting approach to users using unsustainable amounts of bandwidth Plus.net have taken their top 0.3% and are going to place them into bandwidth which they will only share with each other, removing the affect of their usage from the rest of the userbase.
Seems as though these guys were really nailing it, one guy who received the letter had downloaded 156GB since 26/10 apparently.

Along with a few of the lucky recipients of this letter being asked to moderate their usage or go onto this seperate BT Central.
The scary part is you'll have about 300 users whose total download ability is 600Mbps contending a pipe of 150Mbps. 4:1 contention and this won't be nearly enough for these guys most of the time. These guys will see severe performance issues at peak and probably a lot of offpeak times, they will however be moved back to the standard bandwidth if their usage moderates somewhat.
Personally I think it's a brilliant idea and wish it were possible on cable, let them enjoy degraded performance amongst themselves rather than affecting everyone else, heck of a price to pay though, and entire 180k a year 155Mbps pipe.
