Well, you will find that much of the power in memcached is in the 
clients.  Each client has its own personality.  I don't know if the perl 
client currently looks at that namespace stuff at all.

No, the get() will stop when it finds a server that is up.  It reapplies 
the algorithm to the servers list minus the server that is down.

Of course, again, this is a client thing.  The PHP client has the 
ability to not fail over and simply return failure if the server it 
chooses can not be found.
