Because I'm thinking about such things: Electric Door Strike for Schlage Locks, 8-16VAC or 3-6VDC. Because if you're going to make the doorbell a Linux server, how about either an RFID reader, or making the doorbell check to see if my smart phone has recently connected to the WiFi network (indicating that I just came home)...?
comments in ascending chronological order (reverse):
I've used a few of these, mostly in the hospital days (I worked maintenance in hospitals). They work, but should not be used for the main doorknob as they usually have a little slop in them, and often won't open under tension. They work best when used for deadbolts or a second latch.
My parents had an outer door to an entrance garden on a contemporary house that had one of these. It was AC, I remember the buzz. (DC one's just click).
This also makes me remember Tony's house. A crazy "end of the world" electrician that, mostly just because he could, put long throw deadbolt mechanisms in the frame of the house that put a 6" bolt into a steel door. The deadbolt mechanism worked off a a magnet switch that you did not notice as he put a key in the normal key slot. There was a keyed mechanical backup under the house number plate. His house was very odd. It also had a water storage tank and filtration system in the basement, lots of "hidey holes", and a generator. What I liked was it looked just like the rest of the neighborhood. He wanted metal roller shades inside of the windows.. but his wife sanely prevailed.

Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
