Hi George,

Tricky question, most network adapters can have there MAC addresses 
changed, I would assume that to be the case with wireless ones as well. 
  You might have to prove that someone also spoofed your MAC address as 
well!

I'd say any amount of encryption is better than none, at least as a 
plausible defence.  But in any case IANAL so take that with a pinch of salt.

Cheers
Mark
