Correction to my earlier post: Para 3 Please read 30 gigabytes in 60 minutes. I wrote 3 gigabytes...

The distribution server and network would fail. If I used multicast and have a 256kbit multicast injection source the upload to all 3000 GPs will be complete in less than 10 minutes. The clients will still be billed for 30 gigabytes if they were being changed for local traffic and the rest of the national network would remain stable, especially for servers colocated with the originating server. <snip>
