[ale] remote iptables administration

[Dan Newcombe]

Got one box to control others (on box to bind them, one box to rule them
all and in the darkness find them).

What I need ot be able to do is have the control box tell box a to
add/delete this iptable rule, or box b, or both.

About the only thing I can think of is ssh with host based authentication,
but am happy to hear other suggestions.  Or I write my own daemon to take
the rules and execute them, but I think that ssh will be a bit more secure
:)
