Be careful with those stats; they might not be telling you what you
think they are. For example, phone clients are characteristically
different than classic ISP clients. A substantial portion, perhaps
majority of Google's use comes from phone clients but the numbers
aren't broken out in those roll-up stats.

Among others, T-Mobile has demonstrated that a v6-only infrastructure
(with some v4 and NAT at the border) is credible and achievable in a
cell-phone environment. A classic small ISP fills a different niche.
