How to run NS with rine only bots/zero bots?, customising rcbot to run with whichbot Options

[dr_aaagh]

Lo all, I'll explain my situation, am (trying) to run an NS server with whichbot (for aliens) and rcbot for rines. Additionally, I only want the bots on at certain times
and for certain maps.
However, this is being a real pain and the rcbots will automatically join no matter what I try. The only solution I have found so far is to reset the server with different config files. Surely there is an easier way of doing this (like an rcbot_on var)?

Additionally, is there anyway of having rcbots only running on maps that have a valid waypoint file? They shouldn't really be running on these maps anyhow.

Another thing, is there anyway of making the rcbots rine only? I have tried setting all the prefered teams to 'team 1' in the botprofiles, but I still have rcbots joining aliens. Fortunately, in most cases, whichbots tend to join faster than rcbots so most of the bots end up on the right team, but its still annoying.

I mean no offence - rcbots are fantastic as marines, but IMHO whichbots still rule as aliens. Maybe Ive got a bugged version, but rcbot alien skulks will commonly stand RIGHT beside rines trying to parasite them to death while the rine takes down the hive. It would be nice to have the two running well side by side.

Sorry for asking so many questions, but Ive looked through the forums and the faqs and found no answers to these questions.
