Unless there is some kind of filtering involved, i don't see the advantage over the current replication approach (despite of bandwidth, maybe). But if I can subscribe to all changes in a bbox or to all changes on ways with a highway-tag, then there's a real big benefit, as i don't have to deal with all changes (which is quite a huge amount of data) but only with those things I'm interested in.
