Ah, but they aren't hashed together. So particular bits represent the 
MAC address, other bits represent the timestamp, etc.

So even if your random generator isn't too good, you can't possibly 
generate the same UUID as any other machine (unlike a scheme that 
just uses random numbers, or replaces the unique MAC address with a 
non-unique IP address).
