Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to supply prompts from a communication platform to a first machine via a network to register a first user with the communication platform. Prompts are supplied from the communication platform to the first machine via the network to the first user to specify a second user and public network communication constraints. A network address to a single-user, non-transferrable communication client that enforces the public network communication constraints is created. Prompts from the communication platform via the network are supplied to a second machine associated with the second user, allowing the second user to send a second user message through the single-user, non-transferrable communication client. The second user message is sent to the first user via a selected public network allowed by the single-user, non-transferrable communication client.

Abstract: A computer-based system for monitoring and improving a user's dietary compliance by providing the user with multiple forms of feedback designed to encourage adherence to a dietary program. In one embodiment the system comprises a personal computer having a commercially available telephony card and a cellular telephone carried by the user. The system automatically calls the user each evening and prompts the user to input whether the user adhered to the dietary program for each of that day's meals. The system accepts and stores the input, calculates whether the user is achieving their dietary goal, and gives the user positive or negative audio feedback based on whether the user is meeting their dietary compliance target.
