Hi Juan,
Thanks for your reply. I was going to look into using stored configs with
MySQL as per your suggestion, until I saw R.I.Pienaar's email :(
Yes, I would certainly use DNS if I could, but unfortunately DNS is not an
option in this setup.
I think I will have to either parse files (eek) or maybe look into that ENC
suggestion.
