I've already admitted dyslexia, and I may have some acid indigestion to
confess to as well now. The posting of the ranking was supposed to be
neutral and I apologize for the URL's. I'm on a windows box and .... :)

Posting the ranking was specifically targeted at:

"Your definition says, "the routing table in a peering

... which I intepreted to mean a network of the
authors caliber - which are likely to be settlement
and default free in the situation as described.

It is important to have an understanding of the
economical practices of these networks, although I'm
not sure if this is on topic. I'd be happy to elaborate
on this over a taco and a coke. :)

Thanks for helping to be clear on the DFZ definition. I
appreciate that.
