Is there a groundswell of *operators* who think TCP should be replaced, and believe it can be replaced?
Operators like inefficient protocols :-)
Operators are probably more interested in the "fairness" part of "congestion" than the "efficiency" part of "congestion." And of course the dreaded congestive collapse.
More seriously -- the question is whether new services will cause operator congestion problems that today's mechanisms don't handle. It's also possible, per the note that some solutions will have operator implications, such as new tuning knobs for routers and/or new funky new DNS records to make it clear which hosts support TCP++. Beyond that, there are likely implications for things like firewalls, ACLs, and service measurements.
I think its interesting because its an attempt to define what the problem is, and demostrate that problem exists. The next phase would be can those
conditions actually occur in the real world.
