I have never actually deployed a system like this so take
this with a grain of salt.  Virtual servers should be able
to do what you want here.  I believe there is a
configuration where you'd have your front end server
dispatching the request to a select backend server through
a high-speed interconnect.  That backend would then send
the response directly to the client via its own net
connection.  You have your traffic scalability as a tipical
http request is quite small and the responses can be sent
over different connections.  I have no idea how the routing
for this works but have a look
at http://www.linuxvirtualserver.org/ for more information.

Btw, if you're just serving static content, why not have an
nfs server and gigabit or multiple gigabit ethernet links
connecting it with your backends.
