The current version of twisted is 2.2, yet the package on extras is 1.3. Could this be updated or simply removed so people aren't tempted to use this ancient buggy version? Twisted is relatively easy to install with it's python setup script, so a package may not even be necessary, especially if it's not going to be maintained.
