Also, in an attempt to redirect the attention and purpose of the question back to the question itself, I replied to the detracting comments by bringing up my original dilemma again, but then this comment was deleted. I don't know if this particular moderator is the one who deleted it (if such a thing is possible), but now it is gone.
These two things together give suspicion credence to the necessity of using serverfault to ask only questions that please the moderators--that that is complicit with the site topicality.
