W3 Total Cache and Pro Sites

Hi

Currently I have W3 Total Cache Network Enabled

This overrides any level setting of Pro Sites

However, if a new user does not set this up write it will cause the server to slow down.

How can I hide W3 from new users? and configure network wide W3 settings by default on new blogs (new blog template would fix the settings issue possibly - but what about hiding the ability to make the settings) ?

Cheers

Johnny
