¿Is the display manager the one that catchs events in the client
(token plugged, content signed...) and send them (the signed content)
to the server?

¿Do server applications behave as if there was a plugged smartcard
connected in the server?

OK, but this seems to be a client solution, not a client-server
solution. I am looking for a way to let thin clients authenticate and
sign content in remote server applications, just as video, audio and
keyboard in X11.

¿Do you know any technology for doing that?

Is it going to be patched?
