The only bit I'm not certain on is dedicating a nic to a jail (more because I havent tried than because I believe it cant be done, I'd expect that the network stack virtualization in 8+ should allow this.) You can most definately run seperate instances of applications in jails. I'd recomend subscribing to the freebsd-jails mailing list (http://lists.freebsd.org/mailman/listinfo/freebsd-jail) for jail specific questions as I've only dabbled with them a little. But a 10 second example [root@seaurchin ~]# jls JID IP Address Hostname Path 1 10.20.0.3 womble /var/jails/womble 2 10.20.0.2 foobar /var/jails/foobar [root@seaurchin ~]# jexec 1 ps ax PID TT STAT TIME COMMAND 8166 ??
