But, as was already noted, even being network bound, client-to-many is likely a better solution from other points of view (like management and/ro failure cases). -- Evgeniy Polyakov -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
