Answer 1

I know this question is a little old but here is my solution.

 // HTML
 // 
 // 

 // cb1 = checkbox 1
 // cb2 = checkbox 2
  var cb1 = getId('cb1'), 
      cb2 = getId('cb2');

  function getId(id) {
    return document.getElementById(id);
  }

  function setcb1() {
    if(cb1.checked === true) {
      cb2.checked = false;
      cb2.disabled = "disabled"; // You have to disable the unselected checkbox
    } else if(cb1.checked === false) {
      cb2.disabled = ""; // Then enable it if there isn't one selected.  
    }
  }

  function setcb2() {
    if(cb2.checked === true) {
      cb1.checked = false;
      cb1.disabled = "disabled"
    } else if(cb2.checked === false) {
      cb1.disabled = ""
  }

Hope this helps!
