So I may have been wrong about jPAM, it was a 2 second google search. But
pulling the python interpreter or JVM into pcscd is logically not
different. In fact I already have a stub that does all of what I described.
Its pretty simple.

So JVM is designed to be embedded as well, see above. Additionally
everything goes away on the so unload.
