I guess the first thing you should do is looking at JC-Emulator as it
is right now. I already know a couple of tasks that need to be done.

This is a short list:
- change behavior of the virtual reader (possibly move it from Java
   into the C code) - maybe here your driver can help
   . the problem is that the emulator must already be up when you
     start PCSC-Lite, so that pcscd can detect a new serial reader.
     otherwise, initialization fails, and pcscd discards it forever.
- finish serialization. It seems to have troubles, yet. Of course
   the idea is to have multiple image-files, corresponding to multiple
   virtual smart-cards that can be inserted/removed from the virtual
   reader. This has been done with Java serialization, but needs to be
   finished.
- test/debug transactionality of operations
   JC transactionality is emulated with the same mechanism. The idea
   is to serialize at every command APDU that terminates succesfully,
   and to reload the previous image-file if a rollback is needed.
- emulate memory limitations, as it happens onto a real JC device.
   The Applet can even allocate 1GB so far, if the host-machine VM
   allows it. I have no idea weather JVM has a way to limit the
   amount of memory that can be allocated to an Applet, or not.

I'm quite sure you'll find smth. else by trying the emulator.

Bye,
