I have 2 node webserver clusters.  the pair afr eachother.  so it's 
basically what you want.

make sure your setting the local read volume to the local disk and 
that'll help your performance.
I think the only value of separating the servers (and using local 
cache translator) would be that when a file is requested on the 
client, it makes one check to a single server, whereas if you have, 
say a 4 node afr configuration where all the clients are servers to 
eachother, you make 3 checks..  if they all happen at the same speed 
it'll be negligible

that'd be fine if you want 4 copies of your data.
