You can use a hidden TextField and copy the text into a 3d-text GameObject. It’s a bit of a workaround as the 3d-text isn’t made to be editable directly - but Unity always finds a way.

I cooked up a little script for you to get you started:

/*  3d-Text Edit
	Editable 3d-text object.
	Put this script on a 3d-text GameObject.
	Note: Make sure to have a collider on the GameObject to register Raycasts
*/

private var inEditMode : boolean = false;
private var storedString : String;
private var textComponent : TextMesh;
private var guiString : String;

function Start () {
	//Store the String
	textComponent = GetComponent(TextMesh);
	storedString = textComponent.text;
	guiString = storedString;
	
	//Visual Aid for Focus (example)
	renderer.material.color.a = 0.5;
	
	checkChars();	//Check so that the 3d-text isn't empty
	fitCollider();	//Set the Collider to fit the 3d Text Size
}

function OnGUI () {
	if(inEditMode) {
		//Make a TextField which sends to the 3d-text GameObject
		GUI.SetNextControlName ("hiddenTextField"); //Prepare a Control Name so we can focus the TextField
		GUI.FocusControl ("hiddenTextField");		//Focus the TextField
		guiString = GUI.TextField (Rect (90, -100, 200, 25), guiString, 25);	//Display a TextField outside the Screen Rect
		
		//Listen for keys
		if (Input.anyKey) {
			textComponent.text = guiString;	//Set the 3d-text to the same as our hidden TextField
			fitCollider(); 	//Resize the Collider
		}
	}
	//Begin Edit on RightClick
	if (Input.GetMouseButtonDown(1)) {
		var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
		var hit : RaycastHit;
		if (Physics.Raycast (ray, hit)) {
			if(hit.transform==transform) {
				inEditMode = true;
				renderer.material.color.a = 1;	//Alpha 100% on selection
			}  else {
				inEditMode = false;
				renderer.material.color.a = 0.5;	//Alpha 50% on deselection
				checkChars();	//Check so the 3d-text isn't empty
			}
		}
	}
	//Exit Edit on KeyCode Return or Escape
	if (inEditMode && Input.GetKeyDown(KeyCode.Return) || inEditMode && Input.GetKeyDown(KeyCode.Escape)) {
		inEditMode = false;
		renderer.material.color.a = 0.5;	//Alpha 50% on deselection
		checkChars();	//Check so the 3d-text isn't empty
	}
}

//Set the Collider to fit the 3d Text Size
function fitCollider () {
	collider.size.x= renderer.bounds.size.x;
	collider.size.y= renderer.bounds.size.y;
}

//Check the Size of the 3d-text
function checkChars () {
	if(textComponent.text.ToCharArray().Length==0) {
		textComponent.text = "NULL";
            fitCollider();
	}
}

/*
//If you want inEditMode on Left Click use this function instead of manual Raycasting
function OnMouseDown () {
	inEditMode = true;
}
*/

Feel free to ask if I left something you wonder uncommented.
