The problem I am trying to solve...
I am trying to develop a network access strategy based on the use of a NAP for my
organization. I am tasked with preparing a whitepaper to address this.

Yes.
What problem are you trying to solve?
>And if so, why? Furthermore, why is so much attention given to one protocol?
I don't really understand this question. Exchange points are
completely concerned with interdomain routing. The only standard
protocol for interdomain routing is BGP.
> Is it the only protocol for the job of exchanging routes at the NAP level?
Yes/
> Finally, will BGP continue to be the protocol of choice as IPv6 develops?
Yes, that is one of the purposes for BGP address family extensions.
