I prefere to have a sap implementation as bluez plugin, but we need to define api for sim operations which could be implemented in ofono or other proprietary stacks. I guess dbus was intended to be kind of hw abstraction api. > Some time ago Claudio sent proposal implementation of sap server where he defined api for a driver to sim. I still don't see this as a really good idea. We want modem abstraction inside oFono and not all over the place.
