Require set of auth mechanisms

[Nick Anderson]

Is it possible to require a set of authentications.
For example allow login if pam_usb and pam_thinkfinger succeed or unix 
password? That would require you to have the usb key AND your finger (no 
password needed), if you don't have both you only need your password.
I have searched around and It looks like there was a pam_if at one point 
and some talk about different ways to implement something similar to 
this. I just can not seem to find if it has been done.

Thanks
