El Reg reports that:
Ofcom has decided that only fixed line ISPs with more than 400,000 subscribers will be forced to comply with the Digital Economy Act's controversial anti-filesharing provisions.
The communications regulator has informed the Internet Service Providers' Association of the benchmark, and said it intends to publish rules within the next two weeks. The decision marks the swift conclusion of talks we reported on towards the end of April.
It means mobile broadband operators will be exempt from the system. The fixed line ISPs that will be required to send warning letters to customers and potentially throttle their bandwidth or temporarily suspend their access are: BT, TalkTalk, Virgin Media, Sky, Orange and O2.
KCOM, which has less than 400,000 subscribers but does have a monopoly on fixed line internet access in the Hull area, is also likely come under the regime
IDNet and other niche ISPs could suddenly become very popular.
