More seriously -- the question is whether new services will cause operator congestion problems that today's mechanisms don't handle.

and, it includes the questions of what operators will be willing to deploy. One of the questions on the table, for example, is whether the network might be willing to characterize available capacity on links in datagrams that traverse them, either in an IP option or some interior header such as an IPv6 hop-by-hop option. The canonical variants there are XCP and RCP.

As I understand it, the conference organizers want to do something about TCP, but the examples of why it should be done that they are bringing up related to video and other applications. So this is going to have to extend to some variation on a session layer (SIP, for example), and potentially protocols like dccp.
