I'm evaluating the SAP mobile platform and looking for a way to connect with a pure web application (HTML5, JS, CSS) to SUP (without the SAP NetWeaver Gateway). I'm aware of the REST API introduced in SUP 2.2. As 2.2 isn't available yet, are there any other options?
Besides that, I haven't found much information about the plans/ roadmap to support Win 8 (Phone, RT, Pro). The upcoming REST API is one way to go, others?
