Re: 100 Mbps
FTTP/H (fibre directly to the premiss/house) very rare and costs a lot of money
I wouldn't say it needs to be.
Our local ISP has been doing this for a few years now, and their prices are very reasonable imho.
They charge £450-500 to connect you to the cabinet, and that includes pulling fibre from the cabinet to your house and wiring up the fibre-to-ethernet adapters.
People in the UK might think the monthly cost is steep (~£55/month for 25/25mbps, ~£65 for 60/60mbps and ~£115 for 100/100mbps), but they DO deliver that speed continously, both on and off peak hours, and it's not THAT much more expensive that a good DSL package.
