I try to explain with my poor english and poor Circle knowledges :

DHT : Distributed Hash Table. A node has a unique identifier, and 
storing a key/value pair on the ring will store it on the node wich has 
an ident closed to the key. I suppose Circle works on the same basis, 
right ?

by "replication", I mean : if you store a hash on your DHT, the system 
will automatically (or uppon request) copy this key/value on the 'k' 
nearest nodes. Then, if one node fails, the other will keep the value. 
Some systems are able to guarantee that always 'k' nodes store the hash, 
by automaticaly propagating the replication in case of nodes failure.

by "localisation", I mean : the system take care of the "distance" 
between nodes. The distance is a set of number, like : network speed, 
network geographical proximity, network bandwidth, etc. In this way, if 
you have a key/value pair replicated on the ring and you're asking for 
this value, the "closest" node will answer.

I hope I'm more clear.

mhh, I thought I've read your home-page - but I didn't. Sorry. It works 
well on win32 when using your links. The win32-gtk port I was using was 
the cause of the problem.
