<3 Mr.Floppy. It'd be a good idea to add "ambient" to the list in the SVN and make it default in the next release.
@GreaterBeing: I'd hate to use the term impossible... But I can't see a practical way of coding a knife-only mode using CubeScript in a map cfg file. You would definitely need the willingness and cooperation of all clients who use the mode, since I believe having "alias" in the scontext.cfg file means the map config file can only define the alias, not necessarily run all the commands inside it. Thus, the clients would have to cooperate by typing the name of the alias(es) you defined in the map cfg file in order for it to work.
You'd have to consider the possibility of players choosing not to type the command.
