What about https://256.makerslocal.org/wiki/index.php/USB_Auth , it can be adapted to any door with a deadbolt and uses something that most everyone already have.

If we use a stepper motor there will be less turning resistance, though we'd have to use switches or Hall Effect to know where the deadbolt was. Alternately, set the nails at 90° instead of parallel (maybe closer to 120°), then have the servo turn 90° then return to center, so it will always try to put the deadbolt where it wants to, but will just turn freely if the deadbolt is already there.

Here's a video explaining how it works: http://www.youtube.com/watch?v=JKTXRlaXLDQ

Konsgn-> RFID Door lock, Taped to the the door at AlphaOne,

Currently reads RFID tags, then displays them on an lcd screen. door lock would need to be built for it to actually function properly. Was thinking motors and pulleys that would be attached to the wall with magnets. That way it can be taken off easily.

Nice! How about we laser cut a mount for the screen / arduino and coil and screw it over the last left window panel? It would be the triangular spot on the left when looking out. Also we can run another network cable out there for the network shield so we can change the display online. A few wires came out from the door closing, the screen is blank.
