Now that is what I have in mind. For me this is esp important where I have 
something nasty like a guy hosting a bunch of forums that are always not 
getting updated and getting defaced or worse. Until now I have had a dirty 
machine for stuff I know could lead to problems like that. But that brings 
up another question, how far isolated are different instances from each 
other really?
