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.

Cheers,

Joe
