Thanks for the reply.

Yes, exactly.  (Except that, afaict, we also need to do the same thing 
for the pubshm file, pid file, events dir, and the ipc dir in general).

The issue is that there will be N client machines, running the Spice 
client software, with N physical card readers.  There will be 1 
application server, running N different Xorg sessions.  For simplicity, 
let's say that we have N instances of xdm running.  The challenge is 
that, with an unmodified pcscd, there would be 1 pcscd, with N emulated 
cards.  So each xdm would see N different cards.  The the desired result 
is for each xdm to see only 1 card (and, obviously, the card that is 
connected to its session).

Does that help clarify?
