Unfortunately I don't have anything particularly constructive to add, just that I hope this does take off - it's definitely needed and I would be a customer.

The reason I'm not a customer yet (and there is a domain or two I'm toying with picking up) is that I don't know that you are going to be around next year, and I've no idea what happens to my domain in that situation. As much as I hate GoDaddy, I don't see them disappearing any time soon so unfortunately that's where most of my domains currently are. Can you do anything to reassure me on either of those points? Do you know how much you need to make to stay in business and make it worth your while, and how likely are you to meet that?

Best of luck!
