I think it would be a lot of fun to play with a group of maybe 6 friends, utilizing a modified version of Magoth's bot code. It could have a GuildWars feel to it (not Image's GuildWars, but the commercial namesake), having bots available would help keep you from having to rework every encounter. I also really like the idea of cutting diffs of your database for modular distribution.
We started out with ax_classic, and have been modifying it as time goes on. At this point (though I truly appreciate what Angelox did for us) it doesn't look anything like the Ax database. It would be cool to make certain (completed or revamped) zones available to the public like that.
Someone should set up a site for it. I'd play along.
