"only qualified candidates"
What does that "qualified" mean, exactly, hm?
How are you going to establish trust, exactly? Verisign? They're not trustworthy.
Will you be transparent and, say, maintain a public list showing just why this dotbank SLD was given to just whom and why they were deemed "qualified"?
And a bunch of other questions. It'll probably be about as useful as .edu again: mainly 'merkins. They're not the first and far from the only ones, ensuring only half-baked ideas survive.
We really ought to move most now in "the historical generics" under .us. A .bank.us would make more sense. It would be useful if the purported .bank peeps can manage to make the thing truly international, transparent, and actually trustworthy, just like trustworthy banking would be useful. But I doubt they'll even try.
And I doubt ICANN will be any help. They're what looks suspiciously like a nonprofit gone for profit after all, and not at all looking out for the long-term good of the internet community. Unless that's somehow the same as looking out for the long-term profits of the global corporate community.
