I've got it set up so when you edit code on the server it updates the code on the clients too. I found this useful in GMod, where you could open a listen server and have the game hotload around the clients while you develop live.
A couple of bonuses came from this. We should be able to have the stylesheets for the UI hotload too. And we should be able to let modders create their own custom string tables for whatever they want.
