So just to update, our attorneys in washington have not found any other exclusion requests at this time, if ours are the only ones that go in we will put up link for positive comments and support.  We have multiple being submitted to cover multiple applications of the technology and interpretations.  This is an expensive process and hopefully benefits the industry as it needs some help right now with current prices.  We will accept high fives in return at the next consensus if it works out.
