said by Wilsdom:Making money is complicated and requires innovation. For example, consolidate the nodes: one node per region is much more efficient. Meters have trouble billing by the gigabyte, so bill by the bit! (I know, it's amazing you didn't think of something so obvious) If everyone just sticks together and hunts down the bandwidth hoarders we can do this!
no combining nodes is not efficient and never will as you are loading to many subscribers on to a single node which two previously served. There is a reason for nodes splits not node combines more bandwidth with a split not a combine.
