Seems the only problem would be the ridiculous bandwith restrictions UK ISPs put on their ADSL services.
UNLIMITED! in the UK means “LIMITED!”
I estimate at least 300kbps up would be necessary. In the UK they don’t even advertise their upload speeds. No, it’s not SDSL. That’s still basically a leased line and costs £250 a month (although BT have the neck to talk to you about 1:10 contention ratios on what is effectively an SDSL connection but at leased line prices. Rip Off Britain again.)
So. How do I watch UK telly using this thing without falling foul of ISPs “fair use” policies? I accept the thing will need an ADSL connection all of its own… I mean I am happy to pay £20 a month to watch UK TV - even if it’s terrestrial TV only.
