Gordon, you are using the right term.  There can be technical
reasons  why you do not want to coerce networks to peer.  For example, 
2 NSPs connected to a NAP might have some other exchange point where they 
are exchanging traffic (peering).  They should have the flexibility to 
choose how they want to peer.  Also, it is possible you might only 
want to peer at only a few  of the places where you could possibly 
peer with another NSP, thereby reducing the total amount of routing
information in your system.

There are advantages to many NSPs peering at  the "same spot" as can 
be evidenced by the existing practices at the CIX and MAE-East.
It makes thinking about the system more tractable, it simplifies 
debugging the system, it simplifies the routing strategies used by 
NSPs, it makes it easier to plan deployment, it makes it easier for 
users to grok what their pings and traceroutes are telling them, etc.
It also makes it easier to plan and engineer inter-domain backup in the
event of NSP failure.
