I seem to recall the developers take some care to make sure they  
_disable_ buffering to avoid excessively delayed delivery (to the IS)  
that can result in the duplicate suppression to fail.

There are conflicting needs here:  large downlinks with good  
throughput for downlinks vs. small uplinks with low latency  
tolerance.  Not sure what the answer is, but a filtered feed will  
significantly reduce the bandwidth requirement on the downstream side  
of the connection.
