There’s a memorable scene in the movie “Jaws” when Richard Dreyfus, in his role as a shark investigator, finally sees the shark he’s been trailing. “We’ll need a bigger boat,” he says as he realizes how difficult it is going to be to corral the beast. Sharks are notorious for being attracted to blood in the water. It drives them into a feeding frenzy. The same could be said of WLAN equipment vendors when they sense a weak member in their herd, much like Aruba Networks’ aggressive move against Nortel.
