      <p>Still in active development, getting close to having code to post here</p>

        <p>Happy to hear that. What ZF version are you targetting? Does this object need to modify the Zend_Barcode_Object_Abstract (as the ZF1 version is designed for 1D Barcodes)?</p>

          <p>Was originally designed for ZF 1, but will be ported to ZF 2 fairly easily. </p>

          <p>Don't actually need to modify Zend_Barcode_Abstract to do the 2 dimensions...currently I just implement the _prepareBarcode() and _drawBarcode() methods taking into account the extra dimension and it works great.</p>
