If you wait a bit you will get code for the second
suggestion. We currently have a working version that
forwards the apdu to a local client transforming this into
SAP and speaking with a SAP server that uses pcsc to talk to
a SIM card in an external SIM reader. My goal though is to
transform this into a complete SAP client in
sap_interface.c, I will work on that now...
