While that will get you a v6 IP with no problem, there's not currently a
system in place in Router Advertising to assign DNS servers (odds are you're
still using IPv4 DNS unless you've manually put IPv6 IPs into nameserver
entries in /etc/resolv.conf).  Also, there isn't a way that I'm aware of to
assign specific IPs based on MAC address using rtadvd.  For the SOHO, rtadvd
will be fine, but in a larger enterprise, the DHCPv6 protocol will be pretty
much required.
