I'm not trying to advertise, but Beaker browser does a real good job of making p2p delivery transparent to the end user. It's probably slower than most sites in normal usage, but certainly acceptable speeds for static sites, and it performs better under the hug-of-death a site gets when posted on Hacker News. :)

Plus, it already has existing methods to map DNS records or servers to the p2p records, so I can access dat://beakerbrowser.com/ or dat://epa.hashbase.io/ and get it served across the p2p network or pull it up offline if I've viewed it before.
