Although I haven't pestered Greg Stephens about the timing yet (and I suspect the date will be "when it's ready") it looks increasingly likely that Greg will be releasing a public version of the excellent set of scripts he coded to run Zwol, (which, if you haven't visited, is a great site with comics by Greg and others and a healthy discussion forum) which he has labeled "ZAS" or Zwol Archive System. Check out the recent updates in Greg's "The Latest Word" column on the front page of Zwol.
