If you connect the Burster to another Queue, then the downstream ToDevice will 
get those packets pretty much when the Burster lets them through:

Queue(2000) -> Burster(i,n) -> Queue(n) -> ToDevice(eth0);

Alternatively you could write a version of Burster that acted more like a 
Shaper, i.e., had pullinputs and outputs.

This I don't know.  Are you sure that packets are ever entering the Queue?

InfiniteSource -> Queue -> Print(ok) -> Burster(1,10) -> Discard

works fine.
