I'm not a lawyer, but I think the bar for contributory infringement is much higher than that. I think you'd have to find representatives of the defendants actually indicating somehow that people should use it that way. It seems to me that Grokster, etc.'s encouragement of their users to infringe copyright was an important factor in them losing this case, for instance.
