I have one of the GnuPG smart cards made by g10 - it seems to me that an
OTR DSA key could be added to the authentication key slot.

The main issue is how we'd interface with the smart card from libotr or
pidgin-otr. Does GnuPG offer some kind of abstraction interface for
third party applications? If so, I think it would be a fantastic idea to
try to to make this happen.

All the best,
