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.
