  1. How future proof is this? by Samir+Gupta · · Score: 3, Insightful

    I believe the NAT traversal is done by routing via super-nodes which are not behind a NAT or firewall. Is this a valid assumption for the future? In other words, what if every host is behind a NAT or firewall -- it seems that way, given the increased security conciousness of hardware and software makers, that sometime in the near future, firewalling will be the norm and default, not the exception?
