Thanks to all the suggestions so far.
I went the "Formula 409" route (dimethyl benzyl ammonium chloride), but after a liberal spraying and two days of a closed case - the smell is still there. It is a little less objectionable - but if there is any smell at all, the mold will just keep growing and eventually I'll be back where I started.
I'll give it a couple of more days, but the Chlorine Gas route will be next - after I get back from the Northeast Side x Side.
APS, the Coffee approach is good for keeping mold from forming. I assume because it absorbs the moisture, but I'm pretty sure that it won't kill a mold colony once it has formed.
In any case, I'm still open for suggestions before I gas the neighborhood!
Thanks again.
