Moreover, when you use /etc/hosts.[allow,deny] you able to put them into
your Custom JumpStart environment (for example, using Jass security
toolkit), so every new workstation will have unified security profile
immediately after the installation.

This is also possible in case of IPFileter, of course, but it's much
better to have such ability from SUN instead of something unsupported
(although - good) from third party.

I have no idea, is it possible to configure SunScreen Lite during
JumpStart, but even if yes, I would prefer to have more traditional
"wrapped" solution.
