Service integration on a network

Described are computer-based methods and apparatuses, including computer program products, for service integration on a network and/or personal service integration on the network. In some aspects, telecommunication services (e.g., calendar, television, phone, location) on a network are integrated using service codelets designed to interface with the services. A default codelet associated with the user (e.g., via a service plan) dynamically calls the service codelets to request information from the associated services (e.g., calendar data) and/or perform tasks with the associated services (e.g., update calendar). The service codelets can dynamically call other service codelets based on the results of their requests for information. The information from the services is integrated and returned to the user. In other aspects, a personal service monitors and stores user requests for services. The stored user requests are processed to determine usage patterns. The personal service processes the usage patterns to determine future requests and/or to determine how to fulfill a request. The personal service processes the request.
