Peter Lothberg is the ultimate optical Internet guru, although you wouldn't guess it from his Web site, http://www.stupi.se, which displays a garden shed with the caption: "The Main Office of STUPI" (STUPI being the name of his company).
All the same, some very powerful people from the networking world come to kneel at Lothberg's feet. Cisco, for instance, says it designed its GSR12000 backbone router with his requirements in mind. And Sprint, we hear, has based much of its Internet infrastructure strategy on what Lothberg says.
Lothberg says that he was sent by God to network the planet. He may be joking.
