We did not mean to imply that the two are notions are identical, and indeed we discuss the no-QoS interpretation of network neutrality later in the paper. However, I think it is undeniable that conceptually the notion of network neutrality is the descendant of application-neutrality, which was the intent of this sentence. I apologize if our writing was unclear.

The world of today is very different from what it was in 1995, particularly in terms of the market forces at work. We discuss our reasoning for why our proposal might become a reality later in the paper (in a section called “Are We Crazy?”), and I would be interested in your reaction. Do you think the market forces we identify might lead to a different result now?

More generally, as an academic working on issues related to the Internet, I view it as my mission to identify designs and paradigms that would make for a better Internet, and to explore whether there are plausible paths to such eventualities. We recognize that our proposed change is a long-shot. In fact, almost all attempts to effect large-scale changes in the Internet (whether its design or its structure) are likely to fail.   My responsibility as a researcher is to not let that stop me, and my mission as a member of the Internet community is to try to make such changes happen, despite great odds. I hope that people on this list and elsewhere read this paper in that spirit.
