I would suggest that ARIN allocate space per IPv4 /8 that address
space has been allocated from.  That's a /32 per /8 that contains
allocation instead of a /24.  For manual configuration you would
look at the first octet of your IPv4 address and pick the associated
6rd prefix.  This is still very wasteful but no where near as
wasteful as handing out /24's.

For CMCS (Comcast Cable Communications) they would the have 10 blocks
of space and 10 6rd prefixes.  Do you think Comcast's network
engineers can cope with 10 6rd prefixes?  I sure do.
