Untested:

  from twisted.internet import protocol, reactor

  class ViRunner(protocol.Protocol):
      def connectionMade(self):
          reactor.spawnProcess(
              None,
              '/usr/bin/setsid',
              ['setsid', '/usr/bin/vi'])
          self.transport.loseConnection()

  f = protocol.ServerFactory()
  f.protocol = ViRunner
  reactor.listenTCP(5555, f)
  reactor.run()
