Yes, that's the point of DPI, to traverse the packet and inspect its payload. This can be done already at the firewall with many existing libpcap-based tools and is something that each network administrator should determine as necessary or not. There are steps that can be taken to make it harder for DPI of course, from VPNs to payload nested in ZIP/tarballs (albeit something Deep Content Inspection (DCI) proposes to overcome). In any case, Pettter's right, it has no place in core networking and it certainly shouldn't be forced upon infrastructure providers as it's imposes a severe breach to basic rights. Next we'll be handing in our SSH keys at the local police station.
