How would you envision that working? If people started asking for a domain you own, you would get billed more because of it? Or would you have to register your desire for a name and give people a chance to say, 'no, i want that, too!'

Either way sounds bad for a legit company just trying to set up their own site, as it gives competitors an opportunity to cost them some money.

If you had something else is mind, please share more...
