An option would be possible but we would state that this is an
unsupported hack.  Scdaemon caches the state of the card and we have
found no way in PC/SC to get a notification from other applications
doing anything with the card.

OTOH, we would be glad to help you implementing the host side part of
that tokend in scdaemon, so that it can be used by all kind of software.
Note that we have a PCKS#11 interface on top of scdaemon and scdaemon
also provides a direct APDU level access to the card.
