Hi Antoine, Nice to see you on the list :) I've never heard of XCAP, but I just went through that PPT. It looks like a great technology.. It seems to be very suitable when you have backend data in XML format and want to expose that data.
In the CardSync protocol however, we don't really have XML data in the backend. We only use it in the protocol. RPPS stores cards in a database, not as .crd files. Also, in the "Update Card" message ( http://wiki.eclipse.org/CardSync_JAX-RS_API#Update_ICard), the XML format is different from the .crd format of a card. So I think XCAP would be overkill here. But I'm not sure, maybe Alexander has a different opinion (he mostly designed CardSync). BTW Antoine, any news on the iPhone Selector? Did you try to build it yourself?
