A new gTLD that starts with its domains pre-registered. Without any conflicts. And with multiple sources for information services. And the same applies in large scale to other sTLD as well. One objection is that many people would not want to have their domains known as a number.
Some countries successfully use variations of it.
Nomenclature for class may be choosed to be numeric codes or names. For those internationally recognized trademarks, it would be allowed to use corresponding .tm domain name. The assignment directly under .tm only would be made in the case of clearly undisputed names. This domain would constitute itself a valuable source of trademark information too. Easy and convenient checking of registered marks.
