@Giofrio I honestly have no idea why Rogers does not allow this... yet they allow casting to Chromecast. Airplay is a trivial thing to enable when you build and sign the app.
The current Ignite TV app on iOS (version 6.10) is almost a year old. Comcast just released a new version of their app (version 7.5) a few days ago, which also runs on the Apple TV. Perhaps we will see a new version of Ignite TV soon... perhaps with Airplay support... perhaps even with tvOS support... or perhaps not... but we can still dream.
