The other problem, as I was told it at OSCON, was that these were not 
high-availability clusters; it's impossible to add a server to an existing 
cluster, and a server going down is liable to take the whole cluster down.  
Mind you, I've not tried that aspect of it myself; once I saw the ram-only 
rule, we switched to something else.
