Is it possible to get two scripts from different objects to talk to each other without assigning objects in the inspector?

Question

Ok, for reference I'm doing a spaceship game in Boo. I have a ship, it is parent to a camera and an empty that acts as an anchor point for a weapon of the player's choice. Each of these potential weapons has a script that needs a variable from a script running on the camera.

Now in my 1st prototype the anchor point empty was actually the weapon itself and was fixed, unchanging. As such I could use:

public Targetscript as Targeting1
public Gpos as Vector3
def update():
    Gpos = Targetscript.GunneryPOS

where Targeting1 is the name of the script attached to the camera, and GunneryPOS is the variable I need to pull. Drag and drop the camera to Targeting1 in the inspector and everything was happy. Now however, with swapping out weapons and possibly having multiple ships I feel like the drag and drop to the inspector is not particularly flexible.

I feel like the answer I'm looking for has something to do with transform.root and/or transform.Find(). I want to say "Hey weapon, you are now part of a ship. Go look for the camera that's also part of the ship and pull GunneryPOS from Targeting1." I'm just not sure quite how.

I'm more familiar with JS but I've used Unity scripting reference to write it in BOO(quite similar after,all?) after reading Peter's comment, here's an example:

//for a specific instance on a specific GameObject: Targetscript = GameObject.Find('theGameObjectName').GetComponent[of Targeting1]();

//or :
Targetscript = FindObjectOfType(Targeting1);
Targetscripts = FindObjectsOfType(Targeting1); //also works

AFAIK, .Find and .GetComponent are considered slow only if used repeatedly. The idea is to store the result in a variable like the example above.
