I want to have a computerized door locking system – to control all of the door locks in my house from one or more places (desktops). How would I go about doing this? It would be nice to be able to hook up a mag-lock through USB or something. It would be even nicer to have some sort of unlocking/locking command-line utility that I could build a GUI around. Anything that will work for Windows, or Linux would be fine.
Thanks.
