The issue is server capacity for the autohost. They run in vitual machines on a computer maintained by mainstream. Mule is pretty resource hungry, so the fact that it does so well with 3 games running at a time on one machine as host is really quite impressive. They are independent of the planetmule site and chat server. We can just be thankful a fellow mule player has gone to the effort to make them. If anyone else can dedicate a high speed connection and a system to support more host, I'm all for it, but no one has stepped up, and I imagine that's because not many of us here have that ability.
Anyhow, thank you mainstream.
Of course if someone does want to offer up another server, you might be able to get the bot software from mainstream.
