Eh. The tech in Move isn't really that much different than the Wiimote. All Move basically boils down to is accelerometers (Wii Remote) and a gyroscope (Wii Motion Plus) with the addition of a camera and a glowy ball.
As proof I offer up this video of some guy who taped a glowy ball to a Wii Remote and wrote some custom software to use with it.
He breaks it down into steps to make it easier to understand.
0:00-0:58 - Just the Wii Remote with Wii Motion Plus attached. Already you can see it really is pretty much true 1:1 motion. Without a camera however it only senses orientation, not it's position in 3D space.
0:58-2:06 - Now he puts the Wii Remote away and holds just a glowy ball. This shows the ability of the camera to track the position of the ball in 3D space.
2:06-3:17 - And now the money shot. He attaches the ball to the Wii Remote and just like that we have the equivalent of a Move wand. Full 1:1 tracking in 3D space. This ought to look familiar to anyone who has played or seen a video of Tumble.
SUPER BONUS FUN TIME!! - He adds a second Wii Remote on top the the monitor to enable head tracking
Johnny Lee style. Then he picks up his WiiStation Move Motion Plus and waves it around. This is what Tumble would play like if it supported head tracking. Neat.
