Justin streams music in real time to radio stations, but it gets problematic. Leo says that the Internet was never designed for streaming music because packets are designed to arrive out of order and be reassembled. Leo uses an ISDN, which isn't super fast, but they are point to point so it's a direct connection. This means he has consistent bandwidth that delivers packets almost instantaneously. Anything in real time can't really be used over the internet. It's too difficult. Telos makes boxes designed to do internet protocol, but Leo isn't convinced it's ready for prime time. Telephone companies don't want to support ISDN anymore because it has a limited market and requires a separate switch.
