Jacob, We're finishing up a custom fab system that ties directly into out user authentication system. We've gone through several revisions (arduino based initially, now we're Make Controller derived, with other off the shelf components and some custom PCBs) that is powered via PoE (makes wiring for installation a relative ease) and very nicely allows us to programmatically enforce limited access memberships, grant access to meeting rooms based on reservations, really just do what ever kind of access restriction you want to program.
The doors hardware itself we're getting ready to open source. The authentication calls are all JSON based using AES encryption, so the hardware is pretty easy to interface with whatever you want to use on the auth server side. We opted to keep our authentication on an external website because we have a nice little load balanced firewall with auto fail over (A nice little atom based system running pfSense. Lots of functionality on the cheap). If the internet is down, the space isn't terribly usable from a work stand point, so losing access isn't much of a concern. That, and with the auto-failover, we're pretty fault tolerant as it is. We're looking at setting up a small internal caching server that can do authentication internally, but there hasn't really been a need as of yet. And price per door has wound up being about $150 or so, not too bad.
