I'd like to hear a specific definition of this, so we could _have_ stats.

Do you mean announcing a more specific route from different origin AS 
than the aggregate?  Do you you want to restrict that to address blocks 
allocated by RIR's somehow, etc.?

I've actually done some analysis on a portion of the routing table to look 
for multihoming; extracting this info, if defined, might not be a problem.
