Err no. iptables is _not_ suitable for userland applications dropping their _own_ privileges. For privileged processes, it's clumsy at best, as iptables does not quite work if more than one applications uses it. That's typically your firewall configuration wizard or some custom admin-made script. As for UNprivileged processes, iptables is not allowed.
As I understand it, Michael is trying to build something similar to SECCOMP, only way less restrictive and way more usable by real-life userland programs.
