Trying to read SDN info in last hour, but can't see definitely that a SAP web service can be available for external appl... without using SAP PI (which we've not used). All diagrams/text seem to indicate XI/PI as dependent component.
I believe you could still configure direct/point-to-point communication without using XI/PI. Web Services/Enterprise Services can be provided/consumed from an SAP system using ABAP proxies, configuring logical ports, SOAMANAGER. But XI/PI is useful in mediated scenarios and has an option to guarantee Reliable Messaging. Below is one link I bookmarked during some research around eSOA from long time back, may be it might be helpful to you. Also, I am pretty sure you can do Synchronous web services/Enterprise Services without using XI/PI (i.e. point-to-point communication) but not sure if you can use Asynchronous services without XI/PI.
many thanks... just in time! yes, this need is for synchronous For async we'll look closer at our Tibco infrastructure instead of PI (ease of plug-n-play)
