Caveat: I'm not sure I know what you're talking about.

That said, the Bamboo DHT (bamboo-dht.org) supports both immutable and 
mutable values.  The interface we allow for OpenDHT (opendht.org) does 
not, but the underlying code does.  It doesn't support atomic 
read-modify-write, but you can easily set a new value for a key and 
remove the old one.  If two clients do this at the same time, you'll 
end up with both values; so it's easy to notice that something went 
wrong and fix it.  Does that fit your needs?
