Unfortunately the copyright issue pretty much put an end to the development. Air services australia charge thousands of dollars for a yearly license and I decided it would not be financially viable. AWIS phonebook was a test to see what kind of android market there was out there. Seeing as the app was free it was a good judge of what could be expected in terms of download numbers for a possible NAIPS app.
Currently the price for the NAIPS app would be so high to try to cover the costs of development that no one would end up buying it.
Also the licensing cost for ERSA/DAPS is even higher which is why OzRunways on the iPhone have to charge a large yearly fee.
