Not entirely. Contention of interconnects, non-homogeneity of
QoS requirement, and an incompletely developed market in L2
interconnect services make this not as trivial as you make out,
and an area of possible innovation for those providing IXP services
(spoken as a customer who can't buy what he wants)...

...& that is a far more interesting question.

Behind that there is a paradigm question - whether that routing (leave
aside for a minute the calls) will operate end to end with a "light middle"
(cf DNS, and as proposing ENUM for routing - or rather as a substitute for
routing), or whether there is to be intelligence in the middle for routing
(cf BGP, and as those proposing TRIP & selling softswitches presumably
support).

It's possible I am reading more into the word "routing" than you meant.
