Physical Authentication Tokens

[Jay Chandler]

Howdy.

Firstly, my apologies for what might be slightly off topic.

Has anyone seen a solution for Fedora / Linux in general that offers  
physical access tokens (similar to RSA's SecureID) for the do it  
yourselfer?  I'm not too keen on spending a few grand for my private  
equipment, but I'd like to be able to apply genuine two-factor  
authentication.

Thanks in advance....
