The hash algorithm based on source IP looks interesting, persistence will be lost on each reload and adapted to the farm size. Worst case, the stick table + peers to synchronise + clear table on reload... But there might be undesirable side effects: if clear table is not done synchronously, then new entries will be replicated... cheers
