I'd be interested in a pointer to that Chris, if you could pass it along.
The only quantitative analysis I've seen of this is here:
<http://www.tcb.net/stuff/danny-ucla-pack.pdf>
It's 3 months of data from 6 monitors. The basic observation is that
around 30% to 40% updates are packed, and these packed updates
carry up to 80% of prefixes -- a density that seems to be fairly consistent
across both iBGP and eBGP monitors.
