Well, the .xxx TLD is a somewhat major thing. There could be some serious legal issues involved. Say for example you paid a ton of money for the domain porn.com and you spent even more developing it. You could make the argument that you then should be given the first dibs to buy porn.xxx and if someone else buys it you might then claim that you own the name rights and lawsuits can start flying. This can be easily fixed by ICM allowing the owners of a .com the option to be the first to buy the .xxx version of their name but they will most likely want to auction off the premium names so this may not happen.

What could eventually be more difficult is if the government then decides that all adult material needs to be on a .xxx. They could easily pass that law. There is no way of knowing if it would hold up in court, but they could pass it. Let's not forget the courts ruled during the COPA trial publishing to the internet is not a guaranteed right so they could rule that you still get freedom to publish your porn, you just have to follow the rules. If this would happen it could make filtering and blocking access much easier. That could be a good thing because freeloaders would be cut down and those that really want porn and are not just surfing out of curiosity would pay/ask for access to it. The problem then comes back to the original problem which is then who owns what. Say they don't allow owners of .coms to get first crack at the .xxx of their name. so now you paid a ton for porn.com, someone else owns porn.xxx and you now have to shut down porn.com or spend another truckload of money buying porn.xxx. Is that fair?

there are other potential issues like some countries simply not recognizing the .xxx extension and other censorship issues. IMO a .xxx would cause more trouble than it would solve.
