otoh, only less than 30 percent of the available ipv4 adresspaces
is used on the Internet today, so there's lots of space left.

But I agree, why not just give adresses to hosts asking for adresses
via dhcp? the netmask usually is /24 anyhow, so if a user needs more adresses
they will receive more adresses, and if they are connected via a LAN they
can talk to each other aswell.
