I would have to agree with the other's, about the hyphen being the only drawback to this being a great domain. Picture some radio announcer trying to do a commercial for this, on the air..."Ladies and gentlemen, for all your global business needs, your best solution is Worldwide-hyphen-Solutions.com...that's right! Worldwide-hyphen-Solutions...(this part is sung) .commmm"
This is where some domain sellers run into trouble. Thinking through the process of a corporation being able to brand whatever domain it is, you are trying to sell them. Is it relevant to their core business? Does it 'ping'? Is it easily remembered? Will it work with print, radio and television advertising with a minimum of fuss? This is why hypnenated domains are so rarely used in commerce...they are a nightmare for the advertising executive.
Just my $.02...
