does anyone understand how .mobi works? It's not just an extension, it's a protocol in that you have to conform to a number of the .mobi guidelines/rules/mandates to have a .mobi presence. Furthermore, there will be significant trademark issues. If the person who owns the .com name makes a claim that they are doing a mobile initiative and require the .mobi extension. the .mobi organization can seize your domain name. this isn't like any other extension.
