So it looks like this vulnerability is here to stay. They just raise the bar from "trivially breakable" to "you need a bit of cloudcomputing effort to break a connection".
You don't even need that, you can crack 56 bits on a home machine.
Keep in mind, DES was 56 bits, and it was brute forced in 56 hours in 1997.
Bluetooth physically requires some time to pass between communication. 2^56 seconds is 2 billion years. I doubt you can try more than 100 times a second.
