Maybe Monty Python said it best:

BEDEMIR: So, why do witches burn?
[pause]
VILLAGER #3: B–… ’cause they’re made of wood…?
BEDEMIR: Good!
CROWD: Oh yeah, yeah…
BEDEMIR: So, how do we tell whether she is made of wood?
VILLAGER #1: Build a bridge out of her.
BEDEMIR: Aah, but can you not also build bridges out of stone?
VILLAGER #2: Oh, yeah.
BEDEMIR: Does wood sink in water?
VILLAGER #1: No, no.
VILLAGER #2: It floats! It floats!
VILLAGER #1: Throw her into the pond!
CROWD: The pond!
BEDEMIR: What also floats in water?
ARTHUR: A duck.
CROWD: Oooh.
BEDEMIR: Exactly! So, logically…,
VILLAGER #1: If… she.. weighs the same as a duck, she’s made of wood.
BEDEMIR: And therefore–?
VILLAGER #1: A witch!

So, here’s my opinion on the future of certifiability. If it walks like a duck, but doesn’t talk like a duck to all the other ducks, it won’t be fully certified. If I controlled the purse strings and had told the country we spent $20 billion on a national network, my guess is that the one criteria that everyone will remember will be the network.

Is my doctor’s office connected to my hospital? If I’m on vacation 500 miles from home and my wife has to go to the ER, is her history there? It either is or it isn’t, black or white. Some will argue that there are shades of gray deserving of pseudo certification, but to the average person on the street, to Congress, to the physicians who’ll have to use it anything short of interoperability won’t count as a win.
