I had this argument at the IPv6 "launch party" in London (an industry bash
designed to push IPv6 adoption).  It was explained to me then, by people who
should know, that the original intention was to merge MAC and IP addresses.

Hence the rightmost 64 bits - the "interface identifier" are reserved for
the MAC address or equivalent, and IPv6 addresses are designed to be
allocated in blocks of /64.  That's why no end "customer" should ever get
less than a /64.

Now I hear you cry, since MAC addresses are in theory unique, there's no
need to give every customer a /64... But there is, really.  MAC fiddlers,
etc.

An obvious privacy nightmare standards have emerged such as RFC 3041; which
I think, Ian, might describe similar behaviour to that mentioned in your
earlier post.
