Didn't we come to the conclusion on IRC? I think the idea was

class WebProcess(process.Process):
      def __init__(self, request):
          self.request = request

      def handleChunk(self, data):

      def connectionLost(self):

and your .epy would look something like

request.write("<html><body>The output of command is:")
WebProcess(request) #you probably have to do something more than this.. 
                    #register it with the mainloop somehow?

Note that this code is guaranteed to be incomplete, but I think that's the
general idea.
