Yes, there's a lot of stuff that comes out of the box with LAMP/DAMP we 
can use for distributed hosting.

But how do you run a distributed reverse proxy? A quick trip to Google 
found references to Akamai's products that require extensive rewriting 
of URLs (in practice, you push every HTML document through a tool that 
'Akamizes' URIs before publishing it.)

It still seems like there's a weak link in there somewhere for the 
attacker to exploit.
