It's always nice to see useful wily scripts.  I don't know if I 
ever posted or sent this one out, but I have a copy of a sam
script someone posted to sam-fans ages ago. It is neat in that
it uses a FIFO instead of a temporary file. It is no where near
as flexibly as what you posted, but I thought you might be
interested...
