Been there, done that, plus enough other "stupid DNS tricks" and "stupid /etc/host tricks" to get me a fair supply of stories best told over a pitcher of Guinness down at the Undergroud.. *Choosing* to hardcode rather than use DNS is one thing. *Having* to hardcode because the gear is "too stupid" (as Joe Greco put it) is however "Caveat emptor" no matter how you slice it...
