mTLD to enforce Web standards in .mobi

Zoxed writes "Builder.com reports that mTLD will force anyone wishing to register in .mobi will require its customers to stick to rules on how their users' Web sites are developed. Assuming this can/will be policed are there any *disadvantages* to the approach ? Could it be enforced in other TLDs ?" That is the real question: How and what effect would be done? And how sterile would an environment like that be?
