What's the use case for using IPv4?

Main reason for using IPv4 today is compatibility with existing devices.
But with official IPv4 adresses becoming a scarce resource you end up with
dozend and hundreds of 192.168.0.0, 172.16.0.0 and 10.0.0.0 networks which
are horrible to interconnect.

So one IPv6 subnet  for every child should be the logical choice to use
with OLPC.

This way every child could use his OLPC to boot a broken OLPC of another
child with an rescue system, without clashing with other OLPC in the area,
as it is common with IPv4 if somebody accidently installs it's own DHCP
server an hand out wrong IPs.

Add an IPv6 to IPv4 Gateway to the 100$ Server and you end up with a system
that should work quite well.
