why not set a flag field on the form, and when they press submit test it, 
if it is true, then fail the submit. You may also be able to do some 
checking on the server side.

var alreadySubmitted;
alreadySubmitted=false

function testSubmit()
{
         if (alreadySubmitted)
         {
                 alert("No way hosea");
         }
         else
         {
                 alreadySubmitted=true;
                 document.<form name>.submit();
         }
}
