I agre, this would not only be an excellant service for users of UltraHal but it would also be a very good demonstration of the technology. I am a consulting nuclear engineer and my company has recently developed a new web based advanced core monitor. This is a software program that monitors a nuclear reactor core and allows engineers to perform calculations. An intelligent bot could be programmed with simple troubleshooting instructions so that the user could solve some of his/her own problems. I am experimenting with the web based Hal representitive for this very purpose.
