Haha... while you are at it check out Qantas "Next Generation Check-in" - use your frequent flyer card to swipe. You then get an sms, and finally a coupon at gate. I think the goal is bag self tagging later. Next Generation Check-in from Qantas

In SIN the GHA SATS have self check in kiosks equipped with bag scales. As far as I know they can print boarding passes but don't think they do... I never see the machines used.
