This is pretty much what I expect. If you give a 4Mbit user 40Mbit, he
tends not to even be able to use 10 times as much, so we can get away
with much higher ratios.
Statistics and graphs i've seen offlist have been very helpful, and
suggest that 1000 100mbit customers is doable on 1GE.
Atleast, today. Next year's (decade?) launch of the YouView platform in
the UK should increase usage a lot, not to mention a service like
Netflix starting in the UK. We have some movie streaming services, but
they generally suck and are quite low bitrate.
Thanks for the thoughts :D
adam.
