	This might be one of those things that you need to get rather in-depth with 
what exactly you want to do before we all stop asking stupid questions like 
the following:  :P

	Does this mean you want to have something that lies "in the pipeline" of 
SOPs(specifically) and behaves like a Unix SOP, except they don't happen to 
worth with std I/O?  I would think that you could still use this by piping 
out to a file then catting it back in(all in the same command call) when 
done.  I'll admit I've never tried this but you might want to take a shot.

	However, you also indicate you want to massage things, perhaps getting rather 
complicated with some Perl coding.  If you're going that route, couldn't you 
do the same thing?  Your Perl code pipes to stdio?

	If that's *not* what you want(in the pipeline, cooked whenever you attempt to 
run something down the line), then I would think simply having your Perl 
script and letting it "talk" to the Houdini session could work.

	Or, again, I could simply be missing the whole thing.  :)
