>From an ISP's perspective - why close ports? The more ports are open, the more traffic the user can clock up. The more traffic - the more you can charge (if they go over cap). Why would any ISP want to block a customer from that? :-)
I can see ISPs in the future offering two kinds of service: Raw internet - everything open and the customer is responsible for whatever traffic they generate. Very very filtered - customer behind an application level gateway and paying not for internet, but for email, web, IM or whatever. Just some thoughts Yuri
