What effect will this have with other TLDs such as .co.uk
English law (I believe) already requires any business website to include full contact details on the site itself, as well as in the Whois.
Non-business domain owners can, however, opt for Whois privacy free of charge.
This seems sensible and acceptable to me, though I doubt that it is rigorously policed.
Other countries have their own rules with varying degrees of strictness.
Don't forget that com/org/net are meant to be global.
