    Hi Greg,
    
    Curious, what is your motivation for this?
    
    At any rate, a quick-n-dirty example off the top of my head would
    look like the below.  Maybe there is a better / more elegant way,
    especially if you care to use Python, but this is the first thing
    that came to mind using the command-line tools:
    
    Contents of file "badlist.txt":
    
    # List of machines to avoid, note the
      backslash 
      # character serving as a line-continuation at the end
      # of each line.
      BadList = \
      foo.xxx.edu \
      bar.xxx.edu \
      alpha.xxx.edu \
      beta.xxx.edu
      
      Contents of your submit file:
      
    executable = foo.exe
      requirements = stringListIMember(Machine,"$(BadList)")==False
      include : badlist.txt
      queue
    
      
    Hope this helps,
    Todd
