First,

Apologies for asking first formulating a question in two ways with contradictory outcomes (yes/no) and then saying "I guess the answer is no" - that was confusing!  :)   I was tired when I wrote it...
so I meant the second question, i.e. my guess was also that heterogeneity *is* growing.

How would you calculate if there was data: I guess what I'm interested in is bandwidth statistics: how often do we see a bottleneck of X bit/s? The Internet-wide distribution of X is what I'm looking for...

Depending on area/market: I'd also be happy to have X for India, X for Europe, X for ... whatever. It's a start!
Ideally citable - some publicly available study I could refer to.

Cheers,
Michael
