Hooks for authenticating with Cryptocard challenge-response cards?

[Joe St Sauver]

Has anyone successfully enabled use of Cryptocard (www.cryptocard.com)
challenge-response one time passwords with INN 2.3? I've looked at 
the authprogs directory in the 11-30 snapshot we're currently
running, but it doesn't look like it includes support for
challenge-response, but just username/pw pairs. 

Thanks,

Joe
