Via Biskero, Adobe published the Mobile Content Delivery Protocol.

The Mobile Content Delivery Protocol defines a mechanism for delivering applications (called channels) and synchronized data sets on which the applications operate (called feeds) to mobile devices. The protocol includes a control-flow mechanism for managing channel subscriptions and application preferences.
This protocol is implemented in the Adobe® Mobile Client and the Adobe® Mobile Server products. It can be used to serve applications and content to the Adobe Mobile Client or to develop a mobile client that can interact with the Adobe Mobile Server.

The protocol is bi-directional, with a client-initiated “pull” component operating over HTTP or HTTPS, and a server-initiated “push” component operating over SMS. The protocol is designed for lightweight content updates personalized according to end user preferences.
