That's not true. You can have multiple IPs in jails. You can have
multiple jails sharing the same IP. You can have multiple jails sharing
the same multiple IPs. So:

jail1: ipv4_ip1
jail2: ipv4_ip2, ipv6_ip1, ipv6_ip2
jail3: ipv4_ip2, ipv6_ip1, ipv6_ip2

will work. But configuration like this:

jail1: ipv4_ip1
jail2: ipv4_ip2, ipv6_ip1, ipv6_ip2
jail3: ipv4_ip2, ipv6_ip1

will not, because jail2 and jail3 share only some IPs. I've tried
configuration like this on 9.1-STABLE around december 2012 and it ended
with panic. So I'm using the configuration from the first example and it
works ok.
