[Pcsclite-muscle] IFD polling

[Frank Morgner]

You can delegate the calls e.g. by using jni.

I am using a simple socket based interface for delegating the ifd requests, see http://frankmorgner.github.io/vsmartcard/virtualsmartcard/README.html VPCD delegates the calls to everything that listens on the other side of the socket. You can find a java implementation of "the other side" in this android app http://frankmorgner.github.io/vsmartcard/remote-reader/README.html
