The requirement is to do one-way delay measurements.  The requirement isn't changing.  I'm just here to educate myself as to how to do the best job we can.

That's why there are some of us who spend money and work on hard problems.  Traceroute already exists.  In fact, plenty of one-way delay measurements already exist.  We're just doing a larger, better one.  Yes, that takes time and money.  "Math is hard, let's go shopping" isn't a particularly interesting argument.
