Ok, so that's fine for detecting such an event - but then again, doesn't the coord detect such an event as well and issue a new View? So we'd need to wire things so we don't reassign buddies twice - when we detect a shun/stop and again when we get a new View. Re: merging, I think the wipe-clean approach is probably the only thing we can reliably do, as there is no way of knowing how to merge data without implementing a call-back for the calling application to handle.
