customers and web servers and level one naps

What are the positions of Ameritech, sprint, pac bell and MFS on two

First having someone at a NAP who is there as a customer of one of the
National service providers... and who may or may not engage in cost free
peering with any of the other NSPs or even with other isps?

Second: allowing such a customer, or an NSP, to attach web services
directly to the FDDI ring at the NAP.

PAIX is doing this. As far as I know the other major interchange provider
are not. I am wondering why.

  Is PAIX a "major" exchange Gordon?
