Other than the fact that any dedicated memcache servers should be run  
on 64-bit boxes at this point - it is way cheaper to run a 10GB+  
process on a single box than to maintain multiple 32-bit boxes with  
3GB memcache processes - I don't have too much insight.  Although  
splitting a memcache process into multiple processes probably won't  
gain you anything, and in fact might slow down things a bit (the  
hashing/connection on the PHP side has to go through that many more  
config entries to determine the correct server to query).  And, as  
mentioned before, I don't believe the memcache process load is ever  
going to be the limiting factor.
