* there is
  if int(sys.version[0]) < 2:
     print "Content-Type: text/plain\n" 
     print "Roundup requires Python 2.0 or newer."

is the content type necessary for the server startup ?

* in HTTPserver.index
  the Content-Type: text/html is displayed in the browser

  either put "HTTP/1.0 200 OK" in front or skip it.
