nls book player app?

There have been rumors in the wind of an nls book player app for ios for a long time now. Does anybody know (or know how to get) any information on the state of this app? As an every day user of the National Library Service, and a long time fan of the program, I am very much looking forward to this app, as are many others I know. I think we would do well to find out how the progress on this project is going, and offer our support as a community to whomever is developing the app. It goes almost without needing to be said that having this app would be a huge asset to many of us. Being able to have access to these books on our i devices, without having to buy a third party device, or use a not very portable table top player from the library itself would be a revolutionary step forward in access to much of the mainstream material that our sighted contemporaries enjoy. Any info or thoughts would be greatly appreciated.
