Maybe it could have an advantage by running several different unpriviledged 
webservers, where users can also test somewhat insecure technology without 
endangering the whole system -> lightweight virtualization. 

For example using one subenvironment per site. 

On the long run (via improved resource management) this could offer the 
distinct advantage that overloading one site won't bother the others too much. 

For example my sites MySQL accesses once overloaded my providers server (I had 
too long logging enabled and got a traffic spike). They transfered my site to 
a different server to keep the other sites in operation (and wrecked my 
database in that process - I had to painfully recover one of the sites via 
archive.org...). 

On a box with advanced resource management, this wouldn't have affected the 
other sites too much. 

There it might even be possible to add free accounts with unguaranteed service 
(when other sites need the power, the free sites get slowed down 
automatically). 

Best wishes, 
Arne
