I also opt for P2P whenever I can, but it does have drawbacks as well, besides NAT. First, both have to be online at the same time. Second, seems many connections are still not symmetric, so sending files are limited by the upload speed of the sender, and together with the first problem, makes the downloaders experience suffer because of the uploader.

With that said, better infrastructure (IPv6 + better connections) can make P2P very feasible in the future, hopefully. Or software that defaults to local connections if it's possible (so if we can find the device via a private IP, use that connection instead).
