The idea itself has been tried several times before. CompuServe (or was that AOL?) was one of the first to have keyword-based navigation. A few years ago, I met an entrepreneur in London, UK, who was building a company through which you create a unique number for yourself, and that gets associated with all your contact details - sort of like a phone number but to all your contact details (a bit like a LinkedIn public profile I guess). There are other variations.
Personally, I find this way of navigation weird and I don't like it. Also, the domain name your service uses (oneryng.com) doesn't really brand the service in a useful way (but I do love the domain name!).
Also, what's your unique selling proposition? I can't see one!
Apologies if I seem a bit blunt. Please correct me if I misunderstood something.
