1) Use TLP-224. Works fine over the Internet and many card terminals speak it.
2) Put an IP stack on the card. Internet Drafts are already in place and ICANN numbers allocated for smart card ports and smart card IP protocol.

I have something in the works for that: I plan to write a generic
resource forwarding framework which would ultimately also be able to
forward smartcards (which need special handling for local PIN entry).
I'm going to use X11's ICE as a transport protocol in the beginning, as
I don't need to care about authentication then -- simply start the
program that exports the reader as root, have it open the reader and
drop privileges, then open a window and announce "If you need a smart
card reader, talk to the owner of this window" in the window properties.
This way, I only need to care about trusted vs. untrusted X11 clients
(which is trivial) instead of finding out who is connected to the local
terminal etc., and I get ssh forwarding for free.
The project is not very far yet. I am basically experimenting with ICE,
as I have never used it before. I expect to have some proof-of-concept
forwarding code for some simple device in about two weeks.
