InterStream will maintain accounts for both consumers and business-to-business relationships for portal management. Initially, the pilot implementation will solely focus on a wholesale business to business relationship through an ISTP namespace registrar. Retail domain name system registrars will be responsible for registering most of the ISTP namespace. During phase III of the pilot, a business to consumer relationship will be established to allow consumers to register their net-top units through the portal. Subscription-based billing, user identification, and other services will be offered to enable management of the net-top units and insure secure playback.
