Hi Alon,

I am a little confused as to what the library really does. Is it a
library to manage iso7816 cards, or is it an emulation library? If it is
hw emulation the library really should be part of qemu.git, but there is
nothing that prevents us to expanding the qemu Makefile to build the
library and then have a separate RPM called qemu-libs or something that
can be installed without the main qemu RPM being installed.

Can you elaborate a bit on how spice uses libcacard? I can understand it
relying on a library to access/manage smartcards, but the emulation bit
puzzles me?

If libcacard does both card management and emulation, my next question
is whether it wouldn't make more sense to split the two into two
separate packages?

Cheers,
Jes
