RE: ARIN IP6 policy for those with legacy IP4 Space

Now I may be talking crazy... 

IIRC, all of IPv4 space maps to a section of IPv6 space. 

<mad hat on>

If one has legacy IPv4 space, but actually talks IPv6 couldn't one announce a prefix much longer than a /64 to map them 
onto the IPv6 universe (assuming people would allow such craziness... perhaps on their IPv4 speaking routers) and 
originate/terminate traffic as normal? 

</mad hat off>

Isn't this all left to the networks to enforce, as usual, but unlike the status quo, these are all valid allocations...

Technical note: I know this breaks lots of IPv6 goodness (no need to enumerate it here).
