Fedora recently put in Yubikey for their packagers[1], although they are only half way there, supporting sudo but not web auth so far. Similar things could probably happen in Debian. I've proposed two-factor authentication as a potential area for a GSoC project[2], two things come up: a)

Hi, DSA are already looking at two factor authentication, but TOTP based rather than HOTP. There are plenty of TOTP calculators that could be deployed on smart phones, etc. rather than requiring DDs to own a YubiKey (and have USB port available... i wonder if my iPad has a USB port...).
