"administrative" is really the good word here.

This entity looks decentralised if you count the servers and look at 
their geographical repartition. But since they are controlling them all, 
it's the same administrative authority. So I guess "administrative" 
should be the word again :)

That's what I understand, even if decentralisation - as it's been said 
by Dave - can be more general. For the academic definitions, it's a mess 
according to [1].

I noticed that federation is not used on [2] but instead:

"Decentralized — the architecture of the XMPP network is similar to 
email; as a result, anyone can run their own XMPP server, enabling 
individuals and organizations to take control of their communications 

So... am I XSF-compliant if I use the terms like that:

- centralisation: single administrative authority (it's like a kingdom).

- decentralisation or federation: many administrative authorities 
(states federation).

- interdomain federation: a special case of the decentralisation that 
makes it possible for any entity to become a new administrative 
authority (very open federation).

- distribution: peer2peer (direct democraty)
