Separation of client and server functionality, with corresponding
separation of use of client and server sockets. The ability to _never_
open a server socket on the red interface.

Restrictions may actually be a better mechanism, but I can't stop
thinking of a review of some Linux distribution I read years ago.
Every network application had been split into two packages: a client
part and a server part. No configuration necessary, you could install
the client and never worry about inadvertently running the server, too.

Between client, server, _and ntpq_, however, I'm not sure anymore life
is that easy. The server module probably has to be told whether to serve
time and/or status; before long you'll have strongly coupled modules and
the full functionality of restrictions and you've won nothing.

Groetjes,
