How graceful is the system about making these changes while in

reconfigure to use them, and is there any problem other than less

The memcached nodes don't care. They don't know about each other.
The clients are where the issue is. For example, where I'm using my
java client, I initialize it at application startup time and inject
it where it's needed. This effectively leaves me with no
reconfiguration facility.
Alternatively, I could more dynamically access my client and a means
of pushing a new config into it and the users of the client wouldn't
care at all.
I've mentioned a memcached proxy that I think would be an ideal
solution this problem as well as providing a performance benefit from
multi-process applications. I haven't written any of it yet, though.
