This has been addressed by the IPv6 RFC's (I think....)

"Because of certain privacy and security concerns, the implementation of 
autoconfiguration by a host may also create a random interface 
identifier using the MAC address as a base. This is considered a privacy 
extension because, without it, creating an interface identifier from a 
MAC address provides the ability to track the activity and point of 

So, the way I read this, is that using an algoithm and the MAC of a nic 
as a seed, a unique, short-lived IPv6 address is created without the 
actual MAC address embedded in the IPv6 Address. XP does this by default
(Again, I believe). Not sure about Linux implementations of IPv6.
