Before the year’s out, many Internet telephony programs should support conference calling, call answering, voice-data integration, Web site setups, and other interesting tricks like voice avatars, which allow you to design a voice you like. Probable Internet markets include Internet ham radio, casual social and family communications, event telephony, games, Web tours, talk radio, Web shopping, and “hoot-and-holler circuits.” Right now, hoot-and-hollers act like wide-area intercoms for trading companies that want to alert people in a field to important developments. The lower costs mean that public spaces can be defined at will. For instance, a group of artists might want to connect their respective studios into a group atelier.
