Then he really should get a /48. You're even supposed to get a
/48 when only having 1 subnet.
He could also either set everything up staticly, or use dhcp.
Is there any dhcp client/server that supports ipv6? I know there
is an rfc about it (rfc3315). I just never had the need to use it
yet. The only project I could find about it said it was dead.

An IP address is supposed to be unique. The problem however is
routing. How will you know what subnet to route to based on the
IP address?

Then his only options left are static and dhcp.

Just pick something like ::0 or ::1.
