	That's an implementation detail that's probably covered.  My java  
client will automatically aggregate multiple distinct sequential gets  
that are destined to a single server into a multi-get.  Of course, it  
has to take those client requests and split them across the servers  

	I'm certainly not running a facebook or bloglines, but my  
applications so far are pretty efficient at issuing multiple  
individual requests and just letting the client perform optimization.

	Regarding large installs, has anyone considered a memcached proxy?   
It seems that a lot could be gained by having a local proxy on your  
frontend servers maintaining backend connections and configuration  
and perform the optimizations my java client performs (converting  
individual gets into a single get and optimizing out duplicate gets  
without otherwise processing requests out of order) even across multi- 
process clients.
