Wow, a blast from the past.  The *current* IPv6 design was selected to a
good extent because it was *easier* to do in hardware than some of the other
contenders.  You think 64 versus 128 is tough - think about the ASIC fun and
games to support *variable length* addresses (not necessarily even a multiple
of 4 bytes, in some of the proposals. Could be 7, could be 11, check the
address length field for details. Yee. Hah).
