System's not fully reliable at Amsterdam, but being tinkered with. Last summer there was constant backup by border agents to assist and do manual checks in case of failure (about 20-30% of attempts seemed to fail in the time I was standing in line waiting to get through), as well as do spot checks to validate the machines (which at the time were brand new).
No need to "register" anywhere, afaik. At least no signs about it (the signs at the time were for all EU passports).

Yes. In NZ and Australia they have the SmartGate system. If you have the passport, you can use it.
You walk up to it, scan your passport, stand in front of a camera for 10 seconds, and press yes or no if you have something to declare. That's about it. Very simple and fast and I'm usually one of the first through to the baggage carousels.
Here's their page on how to use the SmartGate system there. I imagine it works similarly for other countries that support such methods of passport control.

I went through automated border controls in Helsinki, Finland in Sep. 2012. I have a German passport including biometry data. I did not need any special registration.
The procedure is as follows: The machine scans your passport. After that, you have to step inside and look into a camera. If the machine recognizes you, you are let through. That's it.
As far as I can tell, it seems to really be the case that they only use biometry information stored alongside the photograph.
I was actually quite delighted when I went through them. Zero waiting time!
Airport details
In HEL they allow EU, EEA, Switzerland and Japan passports, see their website. There does not seem to be a registration. (More details from the Finish Border Guard)
In FRA they allow EU and Switzerland passports, though apparently you do have to register now. Source. The site also mentions they use an iris scan to identify you. In 2011 I went through automated border control here, but my experience then was the same as in Helsinki in 2012 and did not involve registration or iris scanning.
