The last time we had @cameron and @pmg chime in on it, it wasn't acting as a traditional iBeacon and wasn't solely dependent on RSSI (signal strength). They would be the best to check up with on this.
If I'm not mistaken from my personal research, the UUID that shows up over Bluetooth is one that is unique to the Bluetooth chip and its own serial number.
@cameron did mention in another thread that if someone was interested in direct Bluetooth access, to e-mail email@example.com and I know another group on Twitter is using that info to make a Windows Phone app for Lockitron.
