In the case of releasing captures of guest traffic without asking their permission though, I’m not sure any technical measures would be enough to erase the perception problem, but pseudonymization of all possible identifying values would theoretically satisfy GDPR requirements, for example. After that, it would be extremely difficult (maybe not impossible) without extensive external knowledge to identify users from their traffic.

When I look  at the data from SCaLE, I find that if I truncate the MAC 
addresses by one byte, there are still very few collisions.

In your much more limited situation, I'll bet that you can get away with 
dropping everything except the last couple of bytes and have the traces be
