Ah, who is using/announcince rather than any sense of "ownership". You want to look at the various *flow tools and platforms. Since this is a cisco list and you presumable have cisco kit, look into netflow. For education, check into sflow, jflow, etc. For any useful data, you'd need to have a BGP table containing all the prefixes you care about. Be aware that configuration for destination AS (as opposed to immediate neighbor AS) will still require post- processing to be aggregated in any meaningful manner.
