Regional AS model

Multiple AS, one per region, is about extracting maximum revenue from 
your client base.  In 2000 we had no technical reason to do it, I can't see
a technical reason to do it today.  This is a layer 8/9 issue.

I am particularly interested in operational challenges for running AS per region e.g. one AS for US, one EU etc or I have heard folks do one AS per DC. I particularly don't see any advantage in doing one AS per region or datacenter since most of the reasons I hear is to reduce the iBGP mesh. I generally prefer one AS  and making use of confederation.
