Hey, I have used Ionic before and one of their recently great features is the Ionic View which allows you to quickly upload, deploy and share your apps with other people without without having to worry on publishing your app.
It basically consists of a common app available in the app stores and by just run an upload command you can have it immediately available for download and spread it out.
I know the gaps and caveats between the app stores and that Xamarin Test Cloud is a great feature for test your app in different devices but requires you the automation effort in your tests.
-Just opened this discussion to know the state of the current Xamarin tools in case they provide that functionality or not (maybe in some point Xamarin Forms Player can take this to the next level 
),
-If not, collect different opinions and ideas about it.
Here is some related documentation of the features I mentioned: http://ow.ly/QB59G
