Today, connections are established from the local node to some given destination 
without considering what other connections may exist between other nodes.  For 
example, an app may select a path to connect A to B based on the connection from 
C to D.

I'm just trying to determine how an implementation can make use of MPR to 
understand the best way to expose it.  The use of MPR over just path records 
seems complex.
