Now they can come to you, virtually, through video chat.
Long the darling of science fiction aficionados, video chat has never much caught on for personal calls. But this year, with the technology being incorporated into a widening array of digital gadgets, professionals specializing in one-to-one services are experimenting with video chat as a way to vastly extend their reach.
