How Implement Multiple IPs with WPMU?


Does anyone have info on how to use multiple (even many) different IPs with WPMU?

I have many different users and one thing I'm afraid of is that if one member does something really stupid or black-hat that all my other members might get delisted.

Some are using the method, while others are using the Domain Mapping plugin. I'm mostly looking to be able to put the different domain mapped blogs on various IPs.

Any experience or ideas on how to implement this?
