Fair enough, a ban on globally unique IPv4 addresses for any embedded
system applications seems more reasonable than targeting one type
of usage (Smart Grid) for embedded systems. 

One example that I have seen of using globally registered IPv6 addresses
for nothing more than the uniqueness of the number, was printing out
RFID tags on a special inkjet printer. With just one /64 subnet
allocation
you could print, and discard RFID tags with globally unique registered
IPv6 addresses as identifiers, and you would grow old and grey before
you used up the 18.4 billion billion numbers in that single /64 block.

So wierd and whacky embedded system ideas really should be looking at
IPv6 today. Because with IPv6, we really do have plenty of address 
space to accomodate these ideas without thinking twice about it.
