I think for most memcache installations that is how things are done,  
for two reasons.  First, memcache doesn't concern itself with  
security or authentication.  There just isn't any, and that's fine as  
long as everyone keeps that in mind.  The second, if the only thing  
the memcache server is doing is memcache, then there is no reason to  
put mediawiki <-> memcache traffic out on anything that resembles a  
public network.  I suspect you'll find most folks who have memcache  
run the traffic over a private back haul network.  Often times that  
network is faster as well (gigabit instead of say 100mbit).
