I've been convinced from time I first became aware of abwn that the concept is technically do-able. No doubt in my mind. Convinced also that it could, some day, be profitable. But, can ABWN stay ahead of potential competition? Is there a possibility that ABWN could obtain an an extension to their patent? I have owned ABWN and came close to buying again during this recent dip. Not in for long haul though - yet.
