You can get the fov by doing a single render, but..
Just tried it and the above doesn't work for 3.
So don't really know :/

A hcky way would be to do pixel perfect type thang with the default camera.

set the cubes width and depth to the stageWidth, and height to stageHeight
and
set the camera.z to -900-stagewidth/2

That would give you a cube that fills the stage.

 Problem is that camera.fov always returns 0 to me =\

  I think its the same. Just replace with camera.fov
 
  eg camera at defualt 0,0,-1000 a plane at 0,0,0
 
  var maxheight:Number = Math.tan((view.camera.fov * 0.5) * Math.PI / 180)
 *
  1000 * 2;
  var maxWidth:Number = maxheight * (stage.stageWidth / stage.stageHeight);
 
  plane = new Plane({material:material, width:maxWidth, height:maxheight,
  yUp:false, bothsides:true});
  scene.addChild(plane);

var maxheight:Number =
Math.tan((PerspectiveLens(view.camera.lens).fieldOfView * 0.5) * Math.PI /
180) * distanceFromCamera * 2;
var maxWidth:Number = maxheight * (view.width / view.height);

remember distance from camera would be the distance to the face you looking
at. Not the objects center.

Thank you for answering, John =)

Since the thing I need is exactly distanceFromCamera you mean I should 
do this:
var distanceFromCamera = cube.width / 
(Math.tan((PerspectiveLens(view.camera.lens).fieldOfView * 0.5) * 
Math.PI / 180) *  2)

?

and then
camera.position = new Vector3D(0,0,distanceFromCamera)
?

Anyway I tried the code you posted but (despite that I imported the 
PerspectiveLens package) I keep getting this error:
Main_VideoCubeAway3D.as, Line 341119: Access of possibly undefined 
property fieldOfView through a reference with static type 
away3d.cameras.lenses:PerspectiveLens.

If it helps I'm using a TargetCamera3D and Away3D version 3
