Say you're trying to explain to a group of smart law enforcement-sympathetic people why innovation is a great thing. 

Some messages work:  "you don't want one industry (Hollywood) controlling what another (high-tech) can do -- this is all about money, and Hollywood wants high-tech to bear their costs."  They nod.

Some messages don't:  "through the internet, law enforcement is getting access to more information than you ever thought possible."  They shake their heads.  Nope.  Not a persuasive message. 

The question comes back:  "What's the benefit of P2P to law enforcement?"  Why should we support something that seems to be a place for child porn, spyware, and copyright infringement?

What's in it for us?

If you have any answers, let me know.
