Have a look at the gear from Arbor.  Not cheap but it does exactly  
what you've outlined (i.e. BGP peers with something on your network  
and takes netflow exports).  Based on the flows and your routing table  
it can tell you how much traffic you have heading to an AS you aren't  
even directly connected to.  Nice graphs, lots of reports.  Very, very  
sweet.
