What a mess, but it has a happy ending. 

I now have an Apache sub-folder of my Dropbox folder that contains sub-folders whose names are domains. 

When I create a new folder and point that domain at the machine running Apache, it automatically is configured to host that domain out of that folder. And I can copy files into that folder from any of my machines on my Dropbox network. 

I was finally able to create a NTFS junction using an Explorer add-in that Samir Talwar gave me a pointer to. Bravo Samir! 

As always the Scripting News braintrust not only has a myriad of answers, but has the right one, and we get there quickly in good spirits. 

You guys are the best!!!
