Wouldn`t it prevent 1:1 from borrowing from 1: ? I think I`m 
missunderstanding the ceil. As I see it it is if I fe. have rate 100kbit 
and ceil 100kbit then 1:1 would go at at least 100kbit and can borrow 
100kbit from 1: . Which is in my case unwanted. I want to limit 1:1 to 
100kbit without abilyti to borrow. 1:100 and 1:101 could borrow from one 
another up to the max rate of 1:1 ( 100 kbit) that is what I want ot 
achieve.

thanks,

Anton
