The present invention is directed to a system and method for establishing a point to multipoint communication network. An identity provider communicates with one or more service providers. An acoustic port may have an opening between an interior and exterior of the portable electronic device. Any number of other active ingredients, such as biocides, can also be incorporated into the personal care product. Upon notification of an environmental condition, the software control notifies each processor to adjust its local clock rate synchronously with the other processors.
