In case you haven't come across it, it is an iOS app from Microsoft that allows you to operate an Xbox One / 360 from your smartphone.
The app is partially screenreader accessible, which should mean it's a fairly trivial job to get it completely sceenreader accessible, meaning the general functionality of the console (not games, but TV guide, video, enhanced / supplementary content etc) would become voiceover compatible. It could be a pretty powerful tool, especially when combined with the XBox One's built in speech recognition.
Microsoft have just opened up a call for feature requests for smartglass. I've put in a feature request to improve VO compatibility, but the features are looked at depending on how many votes they get, so please vote for the idea if you think it is a good one:
