It seems clear that Facebook is pushing harder into local contextualization & small businesses with this... They're enabling foursquare-esque features but taking it a step further by providing free beacons to businesses in the US. Does this scare anyone? I'm not too concerned (yet) so long as they keep this info compartmentalized... the "nearby friends" is already somewhat creepy. I bet @scobleizer will have thoughts on this one.

Not really sure what the point of the Facebook Bluetooth® beacon is. Most phones have powerful enough location based services where that would not be necessary.
