No reasonably sized provider is going to do that. There is too much
competition, most of which is based on price. Until the companies creating
the price pressure die (as in die completely, not re-emerge under a new,
slightly different name), there is going to be no financial insentive for
anyone to spend money improving their network. Let me underline, I am not
talking about smaller ISPs, smaller networks or smaller service providers.

Rubbish. CFO speak is what keeps the companies alive. Engineer-speak
typically lands the company in chapter 11. Companies in Chapter 11 have too
many operational decisions dictated by the courts, and those that think CFO
speak would greally hate to hear courts on the topic.

It is possible that _nanog_ subscribers want this. I am not quite clear how
one can make that generalization about those behind kor.net, those in .ru,
.ua etc. Finally,

Last time I checked it was 2004, not 1998. The companies are financed by
revenues that they generate, not IPOs or VCs based on a promise of enormous
payoff sometime down the road. Cash is the king.

Yes, I do. This will level playing field and hopefully force a few of the
big networks out of business completely, decreasing price pressure on this
service. A drop in the price pressure will create an opportunity for those
companies to spend the money (should they want to or be forced to) to be
better internet citizens.
This is just the cold blooded economic reality. The same reality which
dictates that only smaller companies can enfore strict anti-spam policies,
and prevent their customers from behaving badly.
