Really :-)
Here is a quick & dirty patch to enable my Windows Key (mapped to Mod4).
This is from version 1.1.1.

========== at the end of grab_key()  in input.c ==================

 // grab Mod4 as a replacement for the prefix
 XGrabKey(dpy, AnyKey, Mod4Mask ,  grab_window, True, GrabModeAsync, 
GrabModeAsync);

========== modified key_press() in events.c  ==================

static void
key_press (XEvent *ev)
{
 screen_info *s;
 unsigned int modifier;
 KeySym ks;

 s = find_screen (ev->xkey.root);

#ifdef HIDE_MOUSE
 XWarpPointer (dpy, None, s->root, 0, 0, 0, 0, s->root_attr.width - 2, 
s->root_attr.height - 2);
#endif


 if (!s) return;

 modifier = ev->xkey.state;
 cook_keycode ( &ev->xkey, &ks, &modifier, NULL, 0, 1);

/**************** PATCH STARTS HERE ************/
 if (modifier & Mod4Mask)
   {
     rp_action *key_action;
     if ((key_action = find_keybinding (ks, x11_mask_to_rp_mask 
(modifier & (~Mod4Mask)))))
   {
     char *result;
     result = command (1, key_action->data);
    
     /* Gobble the result. */
     if (result)
       free (result);
   }
   }
 else
/**************** PATCH ENDS HERE *************/
   if (ks == prefix_key.sym && (x11_mask_to_rp_mask (modifier) == 
prefix_key.state))
   {
     handle_key (s);
   }
 else
   {
     if (current_window())
   {
     ignore_badwindow++;
     ev->xkey.window = current_window()->w;
     XSendEvent (dpy, current_window()->w, False, KeyPressMask, ev);
     XSync (dpy, False);
     ignore_badwindow--;
   }
   }
}
