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
