memcached to listen on more than one IP

[Just Marc]

Hello everyone,

As memcached's only line of defense is listening on 
internal/inaccessible addresses, the option of making it listen on more 
than one IP address is missing -- I do want it to listen on two private 
networks but not on an externally accessible IP.   Of course this is 
achievable without making any changes to memcached by using basic fw 
rules or other tricks, but that adds unnecessary complexities that are 
not really desirable in performance systems.

That's my wish list item for the next version.

Thanks!
