Note that, at 1Tbps, 500B packet is 4ns long, at 10Tbps 0.4ns.
If we are able to provide 1Tbps at a single port in a single data stream, then for sure we will have the memory. Otherwise we won't have packet buffers and thus the whole discussion is senseless. Today we use DWDM, as we neither have 1 THz optics nor packet buffers ... Until then this here:
Or, can you make already pipelined memory operating at 200MHz 5 or 50 times more faster by 5 or 50 times more stages of pipeline?

Add a piece of DDRAM or RDRAM and make your table as large as you like. Spend anyone on this world a PI, it still will work if build properly ... Technology is not the PI/PA<200 problem. The problem is just a "I DO NOT WANT THIS", "I BELIEVE", "I DON'T LIKE" by certain people. In my personal view the main reason for this is a "loss of face" conflict by those who claim we can't build routers which handle large tables.
