[Twisted-Python] Process Producer, Request Consumer

So somebody asked on the channel today, "how do I get the output of a system command displayed on my .epy web page?" Basically, the <!--#exec cmd="foo" --> type of thing, if I remember my SSI. Now, given the pieces that are in Twisted, it seems like this should be at most two lines long: 1) create Process 2) designate the web Request as a consumer of the Process. except that I don't know how to do #2 quite so succinctly. Can anyone speak on this subject? - Kevin -- The moon is waxing crescent, 5.7% illuminated, 2.3 days old.
