I read about the Yubikey after seeing the link here... it sounds almost 
perfect, but the site says that the key itself does not have any 
challenge/response mechanism.

I understand that the server/client have a challenge/response (server asking 
client for Yubi passphrase, client obtaining it from the key and responding to 
server with it)... I'm gonna dig around some more... I'm liking this.
