I was under the impression that the Distiller app was running under 
Windows.  If it isn't, it doesn't make much sense for it to expect NTFS 
filesystem semantics.

Can't the trigger operation of placing the special text file be replaced 
by that person starting the script instead (perhaps click a button on a 
web page or something similar)?

While I wouldn't call it elegant, filesystem caching makes such things 
efficient enough that you'll never notice them running.  If you need a 
script that looks for a file to appear or expands a wildcard in a 
directory, go ahead and use one as long as you can sleep for at least a 
few seconds in the loop. It's cheaper than having a person rearrange
