[Twisted-Python] Process Producer, Request Consumer

[Kevin Turner]

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?
