Multi IPs in a JAIL?

[Rudy]

There was once some talk of multiple IPs in a jail:
  http://garage.freebsd.pl/mijail5.README
  http://www.freebsd.org/news/status/report-apr-2006-jun-2006.html#Multi-IP-v4/v6-jails

Any way this will every end up in a -RELEASE branch?

I'd love to be able to run this command:
  jail / exmaple.net 192.168.1.105,10.1.0.21 /sbin/ifconfig
and see the output with two IP addresses...
