That's what IA wants to believe. But it's just not the case that legal points aren't "resolved" or "tested" unless exactly the same situation shows up in court and gets ruled on. The law works in large part by analogy. Strong enough analogies can be predicted.

Then there's the citation so many saw coming to a case called ReDigi, about a system for reselling authorized digital music downloads by ensuring there was only ever one digital copy. They lost, too.
There's another case out there, Aereo, about a company offering a warehouse full of TV tuners subscribers could stream from on a one-to-one basis. For technical legal reasons, that involved different aspects of the copyright law. But the case didn't go well for Aereo, either. Or for any of its competitors pursuing essentially the same business model.
