This is NOT a valid example. Very few volume users of bandwidth for downloading large media files depend on the ISPs that host their web sites. Once you reach the point where this becomes a significant bandwidth problem you move your media files to a company that has the ability to host them properly - e.g. Akamai. Your site can still be hosted by ANY ISP, but the download files will be linked and delivered by edge servers. And yes, you pay for this privilege. There is no free lunch. >The ISP will want to either provide these as >multicasts, which instantly creates a walled garden, >or if the ISP is also a multichannel TV provider, >perhaps the ISP will move those files to his broadcast >tier. Again, walled garden. Again, you've got it wrong. ANYONE can access media files from a service like Akamai, if the company paying Akamai to deliver their files makes them available to the general public. That being said, they may use a transactional model to collect fees for the content, as CNN and others are doing, or they may use a company like Alkamai to provision their private networks (Intranets). In the end, I suspect that the telcos will move to a model that will look much more like Akamai than a cable head end. > >I think it all boils down to this.

I agree that small operators will get by using the public Internet without special provisioning for their files. But I disagree that the delivery of large media files to the masses will be restricted to walled gardens. Many content providers are trying to get around the gatekeepers who run the walled gardens. They will seek out services that make their content available to anyone with a broadband Internet connection. You are confusing the walled garden (gatekeeper) business model, with a business model that seeks to bypass the gatekeepers by moving content to the edges of the network where it can be delivers to anyone, including all of the people who get their broadband service from the walled garden gatekeepers. The only thing the gatekeepers can do to stop this is to block access to digital media files that come from competitors. The telcos would LOVE this!
