Matthias,

A couple of comments:

* You mention disable notifications feature for "mobile variant instances". I was wondering if you considered the same for "mobile variants" and "push applications"? Could help admins disable misbehaving apps, and developers manage older app versions.

* API access: during "app registration", developer login seems like a good idea. I am not so sure about "sending" messages though, as this will likely be initiated by a server-side component with no developer in the loop. 

Thanks for the spec! The clear definitions made it very easy to read. 

D.

This the app wants to send notification based on a criteria, the relevant data has to be stored in the business backend. This way the backend app is very flexible on the criterias (e.g. max salary, geolocation, number of children, etc). All this data is NOT directly related to the technical functionality of sending data. The usage of the AeroGear Pipe is highly recommended to store business data on the business backend.
