The PIPE entry does allow the executed program to have arguments. The arguments 
can be based on the product's product-identifier and, consequently, different 
for each invocation. As doing this could lead to a plethora of outstanding 
programs all waiting for more input, using the "-close" option might be a good 
idea. This might be slightly more efficient than a FILE and EXEC pair but I 
wouldn't bet the farm on it.
