The memcached protocol only specifies how a single client talks to a
single server.  Things like hashing, load balancing and fail over are
up to the client.

Solving these types of problems is what distributed computing is all
about.  They are not trivial and sometimes impossible to solve for the
general case.  As an example, see the "two army problem".
