  Sure.

  If we're going to do that, I suggest also reformatting the "clients"
entry to match the "home_server" entry:

nas short_name {
	ipaddr = 1.2.3.4
	secret = testing123
}

  Which may clean up some of the parsing.

  We can keep the "client" parsing code in there for backwards
compatibility, I guess.
