You could do this with JavaScript pretty easily. Assuming you have a UL full of results, your code could look like this (Prototype.js):

var users = $$('#my_list li');
users.each(function(elm){
if(elm.siblings().include(function(s){ return s.innerHTML == elm.innerHTML; }).length > 0){
elm.addClassName('multiple');
}
});
