Is there a way to connect to BZWhll.WhllObj without ActiveX

Question

At the moment I use:

//--- BlueZone Connection -----
function bzConnect( session_id ){
   host = new ActiveXObject( "BZWhll.WhllObj" );
   //--- Session ID ---
   bzConnected = host.Connect( session_id );
}

To connect my page to run commands from IE to BlueZone. I now have a need to move this processing to chrome however I cannot find a documented way to use "BZWhll.WhllObj" in chrome... any suggestions? I cannot use any extensions to load the page as the code is in an extension that needs to be run from a secure source.
