I feel obligated to ask an obvious question:

    Why isn't a Domain Name sufficient to the purpose you have in mind?

While there are arguments that it is inapplicable for some scenarios, this does 
not apply to all scenarios.  So what are the details of the usage you have in 
mind that render a Domain Name useless?
