Tech execs and extreme jocks are making the world safe for plasma-screen shaving mirrors and Wi-Fi window shades. Join Jack Boulware for an exclusive tour of the ultimate wired homes. And please wipe your feet. Behind the gates of Boca Raton's exclusive Polo development, where Spanish-style mansions and palm trees line the manicured cul-de-sacs, one house stands apart. Sprawling across two lots, the 17,000-square-foot monster belongs to Roger Shiffman, the former CEO of Tiger Electronics. There's the pool and cabana � this is Boca, after all � and a three-story cathedral ceiling in the foyer. But what distinguishes the house is its digital guts � the $1 million of electronics that control this audio-video nirvana, and the remote-controlled waterfall, too.
