@andrea_r I’d say that MU isn’t distributed in the way that’s important here, because the data is all stored in the same db, on the same server (at least that’s how it works by default). In a truly distributed network, each individual/cluster of individuals would have full, sysadmin level control over his or her data. WP/BP is still largely under the control of the person who owns the particular machine where the stuff lives – if the owner decides to pull the plug, there goes the network.
