A work item?

    Despite the stated technical merits of a single root,
    I think one needs to reflect on the implications that 
    a few of the world's largest ISPs appear to have made 
    a business decision to use a superset of the ICANN/US 
    Department of Commerce's root zone.

Which big ones? I've never seen any official message about this.
    
    It's claimed that the US had about 100 million Internet 
    users in December 2000. According to New.net's numbers
    (which needs to be confirmed), about 16% of those can now 
    use their alternative root. 

I've seen various claims by various alternative root operators. None
have been confirmed by independent research as far as I know.
