As ubiquitous as smartphones are, especially in IT staff, I'd like to see a proximity tie. You walk in to your office, you sit down at your computer, the computer has already identified your phone and is waiting for a password that can be simple since your phone must be proximate -- it does not fully unlock until you do something at the keyboard. Maybe have a certificate exchange, or in the case of later model iPhones, add a fingerprint swipe. (Yes, I saw the Myth Busters on spoofing fingerprint scanners). Require an additional, stronger, password for out-of-normal-hours access.
I'm not sure what to do about a lost/stolen phone or how to prevent sniffing and spoofing (snoopfing?), but I think it has the potential to be a beginning.
I'd LOVE to see a crypto tie-in for laptops where I have to enter a code in my phone to open my laptop, though it could be a huge problem if your phone died or were lost while you were on the road.
