Hmm.. so you don't just want a list of the directories, you also want to be able to refer to which computer has a specific directory on it. I can see this being possible, but I'll want to test code first. Please note that if this is possible, if you have the same directory name on more than one drive/computer, then you'll get the information for all systems that have a match.
This gets more complicated, but I'll toss it around in my brain and see what I come up with.
