Sorry, hit "send" a little early, by accident.

I'm not sure whether you're being sarcastic, and if I'm not sure, I
bet people who don't know you really aren't sure. So: the only
nominal IXP I know of where that's really been experimented with
seriously is MYIX, in Kuala Lumpur, where it's been a notable
failure. The other 300-and-some IXPs do things normally, with an IX
subnet that people can peer across. So, the advent of standardized .
1Q tags in 1998, preceded by ISL for many years before that, has not
yet rendered the 99.6% majority best-practice passe.
Just a clarification.
