Further entries in the Info.plist file show that the Lowtide is set as "Hidden," so its icon does not appear for launching in the normal SpringBoard icon screen. On the iPad, other hidden applications include Apple's DemoApp for retail emplacement, FieldTest to provide live signal strength and cell tower information, WebSheet.app for Web page display outside of Safari, and a few other items.
Because of this setting, Lowtide would probably be run as a silent service, presenting its interface only when its features were requested. The iPad's camera connection kit software works very much in this way, opening only when a DCIM camera is attached. The iPad would likely respond to streaming Airplay requests by opening Lowtide, if a future version of its OS included the application.
Lowtide is set to run in landscape-only mode, which would not be a surprise for a media-intense application -- or for one that's original native presentation is on a physical TV device.
Of course, you cannot simply transfer the file over to your iPad and expect it to work with the current iOS releases. Several supporting frameworks are MIA on the iPad. However, it shouldn't be long before enterprising hackers get some of this working. Already, TUAW reader AriX has gotten Apple TV's airplayd daemon utility running on his iPhone.
