This is interesting and has potential, but right now it's just getting the hardware going with a better antenna. It'll be much more interesting to see what he finds over the course of a month or so.
I'd think passive data collection would be more interesting (for nefarious purposes), considering that BTLE is widely used for sensors and in particular for sensors that record very personal data like heart rate.

What nefarious things can you do with knowledge of someone's heart rate though?
Spoofing HR and power telemetry for opposing running/cycling/triathlon teams. I'd send it slightly low, say 3-5bpm, so the target overexerts themselves.
While it doesn't necessarily use the heart rate data (maybe some ID gets broadcasted), you probably can use it to track somebody's whereabouts... to know when they are close to a specific location, for example.
There is much better hardware out there. The Ubertooth devices can pick up BLE, and can also plug into basically any antenna you want. It's been a while since I played with it, but a few years ago my ubertooth was grabbing LAPs without difficulty. It's not a dirt-cheap device (150$ all in) but is open and available from a variety of sources.
