Right - I kind of misspoke (mistyped?) originally, so it probably looked 
like I was saying the key had to be plugged into the machine that you'd 
be logging in to (rather than the one you're typing on).

I do like the YubiKey (I really need to order a couple of these to mess 
around with), but am more looking at token-based solutions because I 
might not necessarily have access to plug anything into some of the 
machines I'd be working from (or they might not be PC-type machines with 
USB ports to plug a keyboard-like thing into).

Thanks!
