P2P is definitely a viable solution that makes their job significantly more difficult. It's not nearly that clear what the NSA is doing. I've worked in the NOC and as a datacenter tech at a Regional ISP and we definitely did not have spying gear in our facilities. We had other, regional BGP peers so it's entirely likely your traffic never crossed the Internet to get to its destination. I'm still not convinced they've tapped a significant fraction of anything. The Internet is a complex decentralized network and the NSA most certainly doesn't have the physical resources to tap more than a small fraction of it.
