Hey, this looks like *exactly* what I want to do - if anyone can give me an example to get started with I'm all up for being a guinea pig. I just can't seem to find examples of this, although that doesn't seem that unlikely given the comments here! I just can't see how this gets done from the docs... I would love to help testing this out (I have 3x /23 and a /25 I want to cluster, and there may be more later) and am prepared to help get this functionality production ready (I want it on production servers so it'd better be ready :-)). So please fire away with examples!
