Hi glacket,
I have been working on the same thing for about a year on Android with Estimote BLE beacons (ibeacons) and producing unfavorably results with tasker. Then a couple of weeks ago google announced Eddystone. João Dias (creator of AutoApps tasker plugins) is now working on adding eddystone beacons to a new tasker plugin.
The Estimote Android App has detection of beacons and looks promising. Their website says "Indoor Location requires 2 dev kits" so it is my assumption Estimote has indoor location working.
The following is a link to joao's community discussing Eddystone. You must be a member of the AutoApps Alpha Community on Google plus to see this post!

I will be testing this as soon as it comes out...if it works better then anything I have now I will add it into my "Home Automation - Chaining Voice Commands" Project
