I'm now considering building a battery powered RasPi device that'll rapidly switch the MAC address on the WiFi adaptor and masquerade as extremely busy periods as I walk through a shopping mall...

Seems like you wouldn't need to do that, just do something akin to a DoS where the traffic is spoofed to contain a different MAC? I guess you'd need driver level access to the adaptor though.
Or, maybe you can just send data whilst flipping random bits in the MAC address memory address location?
Sounds like a fun project!
