Can you elaborate on this one a bit for me? At face value the two statements
seem contradictory.

Surely the bandwidth cost of 3x for a 4020 isn't due to its lack of 2-3x
speed of uploads. And with download speeds the same where is the 3x BW
cost of the 4020?

I'm suspecting that its because the 4020 uses an older slotting algorithm
and isn't as efficient at BW sharing as the 7000. Is that the case? Never
having owned the 3rd brick for a 4020, rumor had it, it was using a commodity
IBM PowerPC (405GP) chip to do the software processing, whilst the 7000 uses
custom ASICs. Could the slower processing speed of the 4020 also have an induced
extra cost to Hughes and/or a VAR?
