The problem is on the other side. From Develer's point of view, the 
*incoming* traffic saturates our download bandwidth, and it's unshapable 
for us; the only thing we can try is to drop random ayiyay packets when 
its bandwidth usage is above certain thresholds, but we're unsure that 
this will help: it helps with TCP because of flow control, but will it 
work for ayiya?
