That would be cool
I've been working on a quest script just to add the commands via saylinks to the bots, you have find that post
here Only problem with it, its only feasible for small servers since you have to create a quest for each bot.
Adding the functions you are talking about would be cool though. You could set up a various bots npc's in Tavern's and Inns that you could go hire! It would give people a reason to go to Inn's and Taverns besides to quickly sell something.....
