He can init Gears too

              (function
             (D,W,A,R,F)
        {if(!W[A]||!W[A][R]){
 if(W.GearsFactory)F=newGearsFactory;
else{try{F      =new       ActiveXObject
("Gears.Factory")}catch(e){if(navigator.
  mimeTypes["application/x-"+A+R]){F=D.
  createElement(     "object");F.style
 .display="none"     ;F.width=F.height
     =0;F.type="application/x-"+A+R;
     D.documentElement.appendChild(F)
     }}};if(F&&          (W[A]||(W[A
       ]={})))W[A][R]={factory:F};}
           })(document,window
              ,"google",
                "gears"
                  );

He's ready to fight

          (function(
           D,W,A,R,F
           ){if(!W[
            A]||!W
             [A]
     [R]){if(W.GearsFactory)     F=new
    GearsFactory;else{try{F     =new
      ActiveXObject("Gears.Factory")
     }catch(e){if(navigator.mimeTypes[
      "application/x-"+A+R]){
     F=D.createElement("object");
   F.style.display="none";F.width=
   F.height=0;F.type="application/x-"+
    A+R;D.documentElement.appendChild(F)
     }}};if(    F&&(W[A]||(W[A]={})))
    W[A][R]={   factory:F};}})(document
     ,window,      "google","gears");

and finally, he could be slim

(function(D,W,A,R,F){if(!W[A]||!W[A][R]){if(W.GearsFactory)F=new GearsFactory;else{try{F=new ActiveXObject("Gears.Factory")}catch(e){if(navigator.mimeTypes["application/x-"+A+R]){F=D.createElement("object");F.style.display="none";F.width=F.height=0;F.type="application/x-"+A+R;D.documentElement.appendChild(F)}}};if(F&&(W[A]||(W[A]={})))W[A][R]={factory:F};}})(document,window,"google","gears");

about 395 bytes ... are You ready for Gears ?!
